Introduction to Business Research

Introduction to Business Research

1. What is Business Research?

Business research is the systematic and organized effort to investigate a specific problem encountered in the work setting that requires a solution. It's a process of finding solutions through thorough study and analysis of situational factors.

Key Characteristics of Business Research:

• Organized: Follows a structured approach.

• Systematic: Involves a series of well-thought-out and carefully executed activities.

• Data-based: Relies on collecting and analyzing data.

• Critical: Involves careful evaluation and judgment.

• Objective: Strives for unbiased inquiry.

• Problem-focused: Aims to address specific issues.

- Rigorous: Conducted with precision and diligence.

The Research Process:

1. Problem Identification: Pinpoint problem areas within the organization and define them clearly and specifically.

2. Information Gathering and Analysis: Determine associated factors, collect relevant information, and analyze the data.

3. Explanation and Solution: Develop an explanation for the problem and implement corrective measures.

Types of Information:

- Primary Data: Information gathered firsthand for the specific research purpose.

- Secondary Data: Existing information found in company records, industry reports, archives, etcetera

• Quantitative Data: Numerical data, typically collected through structured questions.

- Qualitative Data: Non-numerical data, such as words from interviews or open-ended questions, or observations.

2. Types of Business Research: Applied versus Basic

Business research can be categorized based on its purpose:

Applied Research

Purpose: To solve a current, specific problem faced by a manager in the work setting that demands a timely solution.

• Characteristics: Directly applicable to a particular organization, with an immediate need for a solution.

• Examples:

Investigating why a particular product is not selling well to take corrective action.

Developing a new sweetener for diet sodas to address declining consumption due to health concerns.

Facebook's "Aquila" drone project to expand internet access to underserved populations.

Basic (Fundamental/Pure) Research

- Purpose: To generate a body of knowledge and understanding of phenomena, often with the goal of building or testing theories.

- Characteristics: Broader in scope, contributes to existing knowledge, and findings may be applied later by others.

• Examples:

- A university professor investigating the factors contributing to employee absenteeism for academic interest.

- Research into the causes and consequences of global warming.

- Studies on online behavior and interactions to understand social and technological forces.

Distinction: The primary difference lies in the immediate objective: applied research targets a specific organizational problem, while basic research aims to expand general knowledge. However, both often employ similar systematic inquiry methods, and findings from basic research can eventually be applied to solve problems.

3. Managers and Research

Why Managers Should Know About Research

- Problem Solving: Enables managers to identify, understand, predict, and control events and problems within the organization.

- Informed Decision-Making: Helps in making better, calculated decisions by understanding the underlying data and probabilities.

- Effective Interaction with Researchers: Allows managers to communicate effectively with internal or external researchers/consultants, defining roles, expectations, and constraints.

- Critical Evaluation of Information: Enhances the ability to discriminate between good and bad research findings, whether from internal studies, external consultants, or academic journals.

- Awareness of Influences: Fosters an understanding of the myriad internal and external factors affecting a situation, avoiding simplistic cause-and-effect assumptions.

- Preventing Bias: Helps managers recognize and guard against vested interests or manipulation of data by internal or external parties.

- Combining Experience with Science: Facilitates the integration of practical experience with scientific knowledge for more robust decision-making.

What Managers Should and Should Not Do When Interacting with Researchers

Managers Should:

- Clearly delineate roles and expectations for both parties.

- Communicate organizational philosophies, value systems, and any constraints (e.g., access to confidential data) upfront.

- Establish good rapport and trust with researchers.

• Facilitate researcher access to employees and necessary information.

- Maintain open and straightforward communication throughout the research process.

- Be objective, focus on problem solutions, and fully understand the research recommendations and their basis.

Managers Should Not:

- Withhold crucial information late in the research process, as this can hinder the research design.

- Allow value system clashes to go unaddressed, as they can lead to significant disagreements later.

- Be overly reliant on "experts" without understanding the basics of research, which can lead to discomfort or poor decision-making.

4. Internal versus External Research Teams

The decision to use an internal or external research team depends on the specific situation.

Internal Research Teams

• Advantages:

o Readily Accepted: Employees in the subunit are more likely to accept and cooperate with an internal team.

o Less Time to Understand: Already familiar with the organization's structure, culture, and work systems.

Available for Implementation: Can assist in implementing recommendations and evaluating their effectiveness.

Lower Cost: Generally less expensive due to familiarity and reduced learning curve. Ideal for problems of low complexity.

• Disadvantages:

Stereotyped Thinking: May lack fresh ideas and perspectives due to long tenure.

○ Susceptible to Influence: Powerful internal coalitions or vested interests might distort or conceal facts.

Perception of Expertise: May not always be perceived as "experts" by staff and management.

Organizational Biases: Internal biases might affect objectivity.

External Research Teams

• Advantages:

Broad Experience: Draw on experience from diverse organizations and similar problems. o Fresh Perspective: Offer objective, unbiased insights and novel approaches.

Access to Sophisticated Models: Often possess knowledge of current, advanced problem-solving techniques through specialized training.

○ Higher Credibility: Their independence can lend more weight to their findings.

• Disadvantages:

- Higher Cost: Generally more expensive.

- Time to Understand: Require significant time to learn the organization's specifics.

- Employee Resistance: May face initial resistance or be perceived as a threat by employees.

- Additional Fees: May charge extra for implementation and evaluation phases.

When to Use Which:

- Internal Teams: Best for simple problems, when time is critical, for routine policy/procedure development, or when cost minimization is a priority.

- External Teams: Advisable for complex problems, situations involving vested interests, when objectivity is paramount, or when the organization's future is at stake due to serious issues.

5. Applying Research Knowledge as a Manager

As a manager, knowledge of research enhances your decision-making capabilities:

- Objective Decision-Making: You can remain objective and focus on problem solutions, making informed choices based on well-understood recommendations.

• Understanding Recommendations: You can critically assess the recommendations made by researchers, understanding why and how they were derived.

• Adaptability: You can judiciously adapt or substitute existing traditions based on research findings, especially in a rapidly changing environment.

- Risk Management: You can take calculated risks with a better understanding of the probabilities associated with different outcomes.

Essentially, research knowledge transforms you from a passive recipient of information into an active, discerning decision-maker who can leverage data and analysis effectively.

6. Ethics in Business Research

Ethics in business research refers to the code of conduct and societal norms that guide behavior during the research process. Ethical considerations apply to:

- The Organization/Sponsor: Should initiate research in good faith, pay attention to findings, and prioritize organizational interests over personal ego.

• The Researchers: Must conduct the investigation objectively, scientifically, and honestly.

- The Respondents: Must be treated with respect, and their data handled with confidentiality.

• Analysts and the Research Team: Responsible for accurate data analysis, honest interpretation of results, and ethical presentation of findings.

Ethical behavior is integral to every stage of research, including data collection, analysis, reporting, and dissemination. Safeguarding subjects' well-being and ensuring data confidentiality are paramount.

2 The Scientific Approach and Alternative Approaches to Investigation

What is Scientific Research?

Scientific research is a systematic, logical, organized, and rigorous method focused on solving problems. It involves:

• Identifying the problem.

Gathering data.

• Analyzing data.

• Drawing valid conclusions.

It is distinct from hunches, intuition, or personal experience alone, though these may inform the process. Scientific research aims for objectivity and comparability of findings across different researchers. It applies to both basic and applied research.

The Hallmarks of Scientific Research

These are the key characteristics that distinguish scientific research:

Purposiveness

Rigor

• Research begins with a clear, definite aim or purpose.

• Requires a good theoretical base and a sound methodological design.

- Connotes carefulness, scrupulousness, and exactitude.

• A lack of rigor occurs when conclusions are based on:

- Too small a sample.

○ Biased question framing.

- o Failure to include important influencing factors.

Testability

• Hypotheses (tentative, testable statements predicting findings) must be empirically testable and falsifiable.

- A non-testable hypothesis is vague or cannot be tested experimentally (e.g., "God created the earth").

- A testable hypothesis can be supported or refuted by data (e.g., "Employees who perceive greater opportunities for participation in decision making will have a higher level of commitment").

Replicability

- The extent to which other researchers can repeat a study using the same methods and obtain similar findings.

- Made possible by detailed descriptions of the research design, sampling methods, and data collection techniques.

Precision and Confidence

- Precision: The closeness of the research findings to the actual reality of the population being studied, based on a sample. Narrower confidence intervals indicate greater precision. For example, estimating a loss of production days between 30 and 40 is more precise than estimating it between 20 and 50.

- Confidence: The probability that the research estimations are correct. A 95% confidence level (often expressed as a significance level of p = 0.05) is a common convention in social science research, meaning there is a 5% chance the findings may not be correct.

- High precision and high confidence make research findings more useful and scientific.

Objectivity

- Conclusions should be based on factual data analysis, not on the researcher's subjective values, beliefs, or emotions.

- If data do not support a hypothesis, the researcher must accept the finding rather than arguing for their initial conviction.

Generalizability

- The scope to which the research findings can be applied to other settings, situations, or organizations beyond the one studied.

- Wider generalizability increases the usefulness of research, but applied research often has limited generalizability to identical situations.

Parsimony

• Simplicity in explaining phenomena and generating solutions.

- Preference for research frameworks with fewer variables that explain the variance more efficiently over complex frameworks with many variables.

• Achieved through a good understanding of the problem and influential factors, often via literature reviews and interviews.

The Hypothetico-Deductive Method

This is a typical version of the scientific method, popularized by Karl Popper, which provides a systematic approach to generating knowledge. It involves seven steps:

The Seven Steps

1. Identify a Broad Problem Area: Recognize an issue or phenomenon that requires investigation (e.g., a drop in sales, low employee morale).

2. Define the Problem Statement: Narrow the broad area to a specific, focused problem statement, including the general objective and research questions. Preliminary information gathering (literature review, interviews) helps refine this.

3. Develop Hypotheses: Formulate testable and falsifiable educated conjectures (hypotheses) about the relationships between variables that might explain the problem.

4. Determine Measures: Operationalize the variables identified in the hypotheses so they can be measured quantitatively or qualitatively.

5. Data Collection: Gather data relevant to the variables and hypotheses using appropriate methods.

6. Data Analysis: Statistically analyze the collected data to determine if the hypotheses are supported or refuted.

7. Interpretation of Data: Draw conclusions from the data analysis, interpret their meaning, and make recommendations. If hypotheses are not supported, this can lead to refining the theory for future research.

Deductive versus Inductive Reasoning in the Hypothetico-Deductive Method

• Deductive Reasoning: Works from the general to the specific. Starts with a general theory, derives specific hypotheses, and then collects observations to test these hypotheses. This is central to the hypothetico-deductive method for theory testing.

- Inductive Reasoning: Works from the specific to the general. Starts with specific observations and moves towards broader generalizations or theories. This is often used in theory generation and exploratory research.

Many research processes involve a "double movement" of reflective thought, sequentially using both induction (to generate hypotheses) and deduction (to test them).

Example: The C.I.O Dilemma (Application of the Hypothetico-Deductive Method)

- Broad Problem Area: Newly installed Management Information System (M.I.S) is underutilized by middle managers.

- Problem Statement: To what extent do knowledge-related factors and openness to change affect the use of the M.I.S by middle managers?

- Hypothesis: Knowledge of the usefulness of the M.I.S would help managers to put it to greater use.

- Measures and Data Collection: A questionnaire was developed to measure M.I.S knowledge, access skills, openness to change, and frequency of M.I.S use.

• Data Analysis: Data were analyzed to identify factors hindering M.I.S use.

- Interpretation: Managers underutilize the M.I.S due to perceived lack of job performance enhancement or lack of knowledge on how to use it effectively. Recommendations included training seminars.

Obstacles to Scientific Research in Management

Conducting 100% scientific research in management can be challenging due to:

- Difficulties in measuring abstract and subjective constructs (e.g., emotions, attitudes, perceptions).

• Challenges in obtaining representative samples, which can restrict the generalizability of findings.

- It may not always be possible to meet all hallmarks of science perfectly, but striving for them enhances scientific value.

Alternative Approaches to Research

While the scientific approach is dominant, other perspectives exist on what constitutes good research, stemming from different beliefs about reality (ontology) and knowledge acquisition (epistemology).

Positivism

Belief: An objective truth exists in the world, discoverable through scientific research.

Goal: To understand, predict, and control phenomena by identifying laws of cause and effect.

• Methods: Emphasizes rigor, replicability, reliability, and generalizability. Uses deductive reasoning, fixed research designs, and objective measures. Experiments are key.

• Focus: Observable and objectively measurable phenomena.

Constructionism

Belief: The world is mentally or socially constructed; there is no objective truth independent of human interpretation.

Goal: To understand how people make sense of the world and construct their knowledge.

• Methods: Often qualitative, using focus groups and unstructured interviews to gather rich, context-specific data.

Focus: The subjective meanings and interpretations of individuals, emphasizing contextual uniqueness over generalization.

Critical Realism

- Belief: An external reality exists, but it cannot be perfectly measured or objectively understood due to inherent researcher bias and the subjective nature of many phenomena.

- Goal: To progress towards understanding the truth, acknowledging that complete certainty is impossible.

• Methods: Employs triangulation (using multiple flawed methods and observations) to gain a better understanding.

- Focus: Acknowledges both objective reality and the limitations of our observation and interpretation.

Pragmatism

Belief: Focuses on what works to solve practical problems. Truth is tentative and changes over time.

• Goal: To generate useful knowledge for practical application.

• Methods: Embraces eclecticism and pluralism, using mixed methods (qualitative and quantitative) suited to the research question.

Focus: The relationship between theory and practice; research is valuable for its practical relevance.

Understanding these different perspectives is crucial because a researcher's viewpoint influences their research questions, design, and methods. It also helps in understanding and evaluating the research of others.

Defining and Refining the Problem in Business Research

Introduction to Business Research Problems

Business research is a systematic effort to investigate a specific problem in a work setting. Problems can arise from situations where there's a gap between the actual and desired ideal state. These problems can indicate areas needing improvement or issues that require immediate rectification.

Examples of Business Problems

• Long delays causing passenger frustration in airlines.

• Higher than anticipated staff turnover.

- Imperfect instruments for assessing potential employees.

• Lack of career advancement for minority group members.

• Underutilization of newly installed information systems by managers.

• Challenges arising from the implementation of flexible work hours.

- Low commitment levels among young workers.

Distinguishing Problems from Symptoms

It is crucial to differentiate between a problem and its symptoms. Addressing symptoms without identifying the root cause will not lead to effective solutions.

The "5 Whys" Technique

The "5 Whys" (or "5 Times Why") technique is a method for getting to the root cause of a problem. By repeatedly asking "Why?" (typically around five times), the underlying cause can be uncovered.

Example:

- Problem: My best employees are leaving the organization.

- Why? Because they are not satisfied with their jobs.

- Why? Because they do not find a challenge in their jobs.

- Why? Because they do not have control over their work.

- Why? Because they do not have a lot of influence over planning, executing, and evaluating the work they do.

- Why? Because we have been reluctant to delegate.

The number of "whys" is a guideline; the goal is to reach the most basic cause.

Narrowing Down a Broad Problem Area

A broad problem needs to be transformed into a feasible and researchable topic. This involves:

a. Making the problem more specific and precise. b. Setting clear boundaries for the research. c. Selecting a specific academic perspective from which to investigate the subject.

Isolating Key Ideas

To bring clarity and focus to a problem statement, identify the key terms (subjects, verbs, objects). Precise definitions of these terms are essential for accessing relevant literature and refining research objectives and questions.

Example:

Broad Problem: "Minority group members in organizations are not advancing in their careers."

Key Terms:

○ Subject: Minority group members

○ Verb: advancing

○ Object: careers

Selecting an Academic Perspective

Choosing a specific academic perspective (e.g., operations management versus management of perceptions) helps in narrowing down the research topic by leveraging existing bodies of knowledge.

Example:

- Broad Problem: "Long and frequent delays lead to much frustration among airline passengers. These feelings may eventually lead to switching behavior, negative word-of-mouth communication, and customer complaints."

• Perspective 1: Operations management to decrease actual waiting times.

- Perspective 2: Management of perceptions to manage customers' subjective waiting experience.

The Role of Preliminary Research

Preliminary research (or information gathering) is crucial for understanding the problem and narrowing it down. It helps answer questions like:

- What is the problem?

- Why does the problem exist?

• Is the problem important?

- What are the benefits of solving the problem?

Types of Information to Gather

1. Information on the organization and its environment (Contextual Factors):

• Company origin, history, business, growth, ownership.

• Size (employees, assets).

• Charter, purpose, and ideology.

- Location.

• Resources (human and others).

- Interdependent relationships with other institutions and the external environment.

• Financial position.

- Structural factors (roles, positions, communication channels, control systems, workflow systems).

• Management philosophy.

2. Information on the topic of interest (Literature Review):

• Textbooks, journal articles, conference proceedings, and other published/unpublished materials. This helps in structuring research and developing a precise problem statement.

Data Collection Methods for Preliminary Research

- Secondary Data: Data collected by others for a different purpose (e.g., statistical bulletins, government publications, company websites, internet).

- Criteria for evaluating secondary data: Timeliness, Accuracy, Relevance, Costs.

- Primary Data: Data collected first-hand by the researcher for the specific study (e.g., interviews, observation, questionnaires, experiments).

It is often beneficial to gather both primary and secondary data simultaneously in the early stages.

Developing a Good Problem Statement

A problem statement should be unambiguous, specific, focused, and address the issue from a particular academic perspective.

Components of a Problem Statement

A good problem statement includes:

1. Research Objective(s): States the purpose of the study (the "why"). It explains why the study is being conducted.

• Examples:

☐ To find out what motivates consumers to buy a product online.

○ To study the effect of leadership style on employees' job satisfaction.

☐ To determine the optimal price for a product.

2. Research Question(s): Specific questions that the study aims to answer (the "what"). They guide data collection and analysis.

• Examples:

What are the factors that affect the perceived waiting experience of airline passengers?

How do price and quality rate on consumers' evaluation of products?

○ Does better automation lead to greater asset investment per dollar of output?

Criteria for a Good Problem Statement

• Relevant: Meaningful from a managerial, academic, or both perspectives. o Managerial relevance: Addresses a current organizational problem or an area for improvement.

o Academic relevance: Contributes to knowledge where little is known, knowledge is scattered, results are contradictory, or established relationships don't hold in new situations.

• Feasible: Can be answered within the restrictions of the research project (time, money, respondent availability, researcher expertise). The scope should be narrowly defined.

• Interesting: Genuinely engaging for the researcher to maintain motivation throughout the time-consuming research process.

Types of Research Questions

Exploratory Research Questions

When to Use: When little is known about a phenomenon, existing research is unclear, the topic is complex, or theory is insufficient.

Approach: Often relies on qualitative methods (interviews, focus groups, case studies). The focus is broad initially and narrows down over time.

• Generalizability: Results are typically not generalizable to the population.

Example: Why do employees in this new factory have low morale?

Descriptive Research Questions

- Objective: To obtain data that describes the topic of interest (characteristics of objects, events, or situations).

- Approach: Can be quantitative or qualitative. May involve correlational studies to describe relationships between variables.

- Purpose: To understand characteristics of a group, think systematically, offer ideas for further research, and aid in simple decision-making.

- Example: What is the profile of customers who default on loans?

Causal Research Questions

• Objective: To test whether one variable causes another variable to change.

• Conditions for Establishing Causality:

1. The independent and dependent variables must covary.

2. The independent variable must precede the dependent variable.

3. No other factor should be a possible cause of the change in the dependent variable.

4. A logical explanation (theory) must exist to explain the relationship.

• Approach: Often uses experimental designs.

Example: Does increasing the advertising budget raise sales?

Note: Exploratory, descriptive, and causal research often build upon each other, with exploratory research laying the foundation for descriptive research, and causal research building on descriptive findings.

Developing a Research Proposal

A research proposal is a formal agreement between the sponsor and the researcher before the study begins. It outlines the problem, methodology, duration, and cost.

Key Components of a Research Proposal

1. Working title.

2. Background of the study.

3. Problem statement (including research objective and research questions).

4. Scope of the study.

5. Relevance of the study.

6. Research design (type of study, data collection methods, sampling design, data analysis).

7. Time frame of the study.

8. Budget.

9. Selected bibliography.

The Role of the Manager

Managers play a vital role in the early stages of research by:

• Identifying broad problem areas.

- Helping to narrow down broad problems into feasible research topics.

• Providing input and context.

• Ensuring the research remains managerially relevant throughout the process.

Managers should collaborate closely with researchers during problem definition and remain involved throughout the entire research process.

Ethical Issues in the Preliminary Stages of Investigation

When gathering preliminary information, researchers must be mindful of ethical considerations.

Key Ethical Considerations

- Informing Participants: Inform employees about the proposed study, even if not revealing the exact reasons to avoid bias.

• Voluntary Participation: Employees should not be forced to participate.

- point.

- Confidentiality and Anonymity: Assure respondents that their responses will be kept confidential and individual responses will not be divulged. Ensure individual respondents cannot be identified in reports.

• Protection from Harm: Protect participants from physical or psychological harm.

• Honesty: Avoid obtaining information through deceptive means.

- Researcher Capability: Ensure the researcher has the necessary skills and resources to conduct the project. If not, the project should be declined.

• Reporting Back: Plan how to report research findings back to participants.

The Critical Literature Review

Functions of a Literature Review

A critical literature review serves several crucial functions in the research process:

- Positioning Research: It situates your research within the existing body of knowledge, demonstrating how your work builds upon or contributes to current understanding.

• Shaping Perspective and Insight: It helps you view a problem from a specific angle, stimulating new ideas and insights relevant to your research topic.

- Avoiding Redundancy: It prevents "reinventing the wheel" by ensuring you don't waste time rediscovering knowledge that already exists.

- Establishing Terminology: It allows you to introduce and define key terms and relevant terminology, ensuring clarity and consistency in your writing.

- Informing Methodology: It provides insights into the research methods others have used to address similar research questions, which can inform your own methodological choices.

• Contextualizing Findings: It helps place your research within a broader academic debate, enabling you to relate your findings to those of other researchers.

The specific functions can vary based on the research approach:

- Descriptive Studies: Help in developing a comprehensive overview of relevant perspectives, defining key concepts, and identifying frameworks and tools for description.

- Inductive and Exploratory Studies: Aid in developing a theoretical background, summarizing pertinent literature, clarifying logical continuities, and identifying methodological issues and controversial areas. It can also highlight the need for further exploratory research due to conflicting or industry-specific findings.

• Deductive and Applied Studies: Assist in developing a theoretical background, identifying key variables and their relationships, justifying these relationships, and developing hypotheses. It provides a framework for the research and ensures no critical variables are overlooked.

Data Sources for Literature Reviews

A comprehensive literature review draws from a variety of sources:

• Textbooks:

- Pros: Cover a broad range of topics thoroughly, offering a good starting point.

- o Cons: Tend to be less up-to-date than journals.

• Journals:

- o Academic Journals: Articles are typically peer-reviewed by experts, ensuring quality. Review articles summarize existing research, while research articles report empirical findings and often include a literature review section.

- Professional Journals: Provide up-to-date information on recent developments and practical relevance.

- Theses/Dissertations: Often contain exhaustive literature reviews and detailed empirical chapters.

- Conference Proceedings: Offer the latest research, which may not yet be published, but require critical assessment of quality.

• Unpublished Manuscripts: Include papers "in press," data from unpublished studies, letters, and personal communications; these are often very current.

• Reports: Published by government departments and corporations, these provide specific market, industry, or company information.

• Newspapers: Offer up-to-date business information but may contain biased opinions.

- The Internet: Provides a vast amount of information but is unregulated and unmonitored, requiring careful evaluation of usefulness and reliability. Resources like Google Scholar can help identify academic literature.

Searching for Literature

Modern technology has greatly simplified literature searching:

- Computerized Databases: Offer significant advantages in terms of time-saving, comprehensiveness, and cost-effectiveness.

- Electronic Journals: Journals available online.

- ☐ Full-Text Databases: Provide the complete text of articles.

- Bibliographic Databases: List bibliographic citations (author, title, source, etcetera).

- Abstract Databases: Provide summaries or abstracts of articles.

• Search Engines: Tools like Google Scholar help identify academic literature.

Evaluating the Literature

Once literature is identified, careful evaluation is necessary:

- Initial Screening:

- o Review titles and abstracts to gauge relevance.

- o Examine the introduction and conclusion of articles for research objectives and questions.

- Consult the table of contents and first chapter of books.

• Assessing Quality and Relevance:

- Key Studies: Include frequently cited articles and books, even older ones.

- Recent Work: Incorporate up-to-date research that builds on existing literature.

- Criteria for Recent Research:

- Clarity and analytical presentation of the research question/problem statement.

- Transparency of research relevance.

- Direct building upon previous research.

- Contribution to the field.

- Guiding theory: Is it relevant, explained well, and convincing?

- Methodology: Is it clearly explained and convincingly justified?

- Appropriate sample, research design, and measures (validity and reliability).

- Appropriate quantitative/qualitative techniques.

■ Conclusions logically derived from findings and answer the research question.

- Consideration and presentation of study limitations.

- Journal Quality:

- Peer-reviewed status.

- Impact factor (a proxy for journal importance).

- Criteria for Assessing Value:

- Relevance of the issues addressed.

○ Importance (indicated by citations).

- ☐ Year of publication.

- Overall quality of the article or book.

Documenting the Literature Review

Documenting the literature review is essential to demonstrate the researcher's knowledge and thoroughness.

- Synthesis, Not Just Summary: A literature review should synthesize findings, combining elements from different sources to form a new understanding, rather than simply summarizing each source individually or presenting them chronologically.

- Referencing Styles: Various citation styles exist, with the Publication Manual of the American Psychological Association (A.P.A) being common in management. Other styles include The Chicago Manual of Style and Turabian's Manual for Writers.

• Purpose of Citation: To give credit to authors and enable readers to find the cited works.

Referencing and Quotation in the Literature Review Section (A.P.A Format)

• In-Text Citations: Use the author-year method.

- ☐ Author in narrative: found...

- ☐ Author and year in parentheses:....

- Author and year in narrative: In a follow-up study from 2013, Green demonstrates...

- Citations within the same paragraph: The year can be omitted after the first citation if there's no risk of confusion.

• Two authors: Cite both names every time.

- Three to five authors: Cite all authors the first time; subsequently, use the first author's surname followed by"et al.".

- Six or more authors: Cite only the first author's surname followed by "et al." for all citations.

• No author: Cite the first two or three words of the title in double quotation marks.

• Author designated"Anonymous": Cite as (Anonymous, 2014).

- Multiple works by the same author in the same year: Cite in the order they appear in the reference list, using suffixes (e.g., 1999a, 1999b).

• Multiple citations in text: List in alphabetical order of the first author's surname, separated by semicolons.

- Personal communication: Cite in the text only and do not include in the reference list.

Quotations in Text

• Exactness: Preserve original wording, punctuation, spelling, and italics, even if erroneous.

• Page Numbers: Always include page number(s) for direct quotations.

• Short Quotations (under 40 words): Enclose in double quotation marks within the text.

- Long Quotations (over 40 words): Set in a free-standing block, indented five spaces from the left margin, without quotation marks.

- Emphasis: Use brackets and "italics added" if you add emphasis.

- Omissions: Use three ellipsis points (dot dot dot) to indicate omitted material.

- Copyright: Seek written permission for extensive quotations from copyrighted works and footnote the permission.

Ethical Issues in Literature Reviews

Two major pitfalls to avoid:

Purposely Misrepresenting Others' Work: Distorting viewpoints, ideas, models, findings, or conclusions of other authors.

• Plagiarism: Using another's original words, arguments, or ideas as your own, regardless of intent (carelessness, ignorance, or good faith).

Both are considered fraud.

Common Forms of Plagiarism

Sources Not Cited:

○ "The Ghost Writer": Submitting another's work verbatim as your own.

○ "The Photocopy": Copying significant portions of text without alteration.

"The Potluck Paper": Disguising plagiarism by combining text from multiple sources with minor alterations.

"The Poor Disguise": Altering key words and phrases while retaining essential content.

o "The Labor of Laziness": Paraphrasing extensively from sources instead of original work.

○ "The Self-Stealer": Borrowing heavily from one's own previous work without proper attribution.

• Sources Cited (but still plagiarized):

"The Forgotten Footnote": Mentioning an author but omitting specific location details, masking other plagiarism.

o "The Misinformer": Providing inaccurate source information, making retrieval impossible.

"The Too-Perfect Paraphrase": Properly citing but copying text word-for-word or near-verbatim without quotation marks, falsely claiming original presentation.

"The Resourceful Citer": Properly quoting and citing, but the paper contains almost no original work.

○ "The Perfect Crime": Properly quoting and citing in some places, but paraphrasing other arguments without citation.

Avoiding Plagiarism

Observe rules for referencing sources.

Consult university plagiarism guidelines.

• Utilize plagiarism detection software (e.g., Turnitin, Ephorus).

Key Elements of a Literature Review

A literature review is not:

• A mere summary of sources.

- A collection of articles on a similar subject without linkage.

• An alphabetically or chronologically arranged list of sources.

- A presentation of sources of equal value.

Instead, a literature review should:

• Link and juxtapose ideas.

- Make the reasons for grouping sources explicit.

- Present information according to its value for your research project.

Critical Literature Review Process

1. Preview: Get an overview of the material.

2. Annotate: Make notes and highlight key points.

3. Summarize: Condense the main arguments.

4. Compare and Contrast: Identify similarities and differences between sources.

5. Synthesize: Combine information to form new insights and conclusions.

Five Critical Questions (Wallace and Wray)

1. Why am I reading this?

2. What is the author trying to do?

3. What is the author saying that is relevant to my research?

4. How convincing is the author's argument?

5. What use can I make of this reading?

Theoretical Framework and Hypothesis Development

The Need for a Theoretical Framework

A theoretical framework is the bedrock of deductive research. It represents your beliefs about how phenomena (variables or concepts) are related and provides an explanation for why these relationships exist. This framework is built upon a thorough review of existing literature and logical reasoning, taking into account the specific context of your research problem.

The process of building a theoretical framework involves:

1. Defining Variables: Clearly defining the concepts or variables that will be part of your model.

2. Developing a Conceptual Model: Creating a visual or descriptive representation of the hypothesized relationships between these variables.

3. Formulating a Theory: Explaining the underlying reasons and logic behind the proposed relationships between variables.

From this framework, testable hypotheses are derived, which are then empirically tested to validate the theory.

Variables

A variable is any factor that can take on different values. These values can change over time for the same entity or differ between entities at the same time.

Types of Variables

There are four main types of variables discussed:

- Dependent Variable (Criterion Variable): This is the primary variable of interest to the researcher. The goal is to understand, explain, or predict its behavior or variability.

- Independent Variable (Predictor Variable): This variable is believed to influence or cause changes in the dependent variable. For a variable to be considered a cause, four conditions should ideally be met:

1. Covariation: The independent and dependent variables must change together.

2. Time Sequence: The independent variable must precede the dependent variable in time.

3. Control: Other potential causes of change in the dependent variable must be ruled out.

4. Theory: A logical explanation must exist for why the independent variable affects the dependent variable.

- Moderating Variable: This variable influences the strength or direction of the relationship between the independent and dependent variables. It has a contingent effect, meaning the relationship between the independent and dependent variables changes depending on the level or presence of the moderating variable.

- Mediating Variable (Intervening Variable): This variable surfaces between the independent and dependent variables. It helps to explain how or why the independent variable influences the dependent variable. It has a temporal quality, appearing after the independent variable has operated but before the dependent variable's effect is fully realized.

Identifying Variables in an Example

Scenario: A manager observes that offering more training programs leads to higher employee productivity. However, this effect is less pronounced for employees over 60 years old.

• Dependent Variable: Employee productivity (the outcome of interest).

- Independent Variable: Training programs (believed to influence productivity).

- Moderating Variable: Age (specifically, being over 60 years old). The relationship between training programs and productivity is contingent on age.

Diagram:

Training Programs (Independent) --> Employee Productivity (Dependent)

(Moderates the relationship)

Age (Moderating)

Theoretical Framework Components A robust theoretical framework should include:

1. Clear Definitions: Precisely define all relevant variables and concepts. Use definitions from existing literature and justify your choice.

2. Conceptual Model: Present a visual or descriptive representation of the hypothesized relationships between variables. This can be a diagram or a detailed textual explanation.

3. Theoretical Explanation: Provide a clear rationale and justification for why these relationships are expected to exist. This explanation should draw from existing theories or logical reasoning.

Hypothesis Development

Hypotheses are tentative, testable statements that predict the expected outcome of your research based on the theoretical framework. They are relational and aim to confirm or refute the conjectured relationships between variables.

Types of Hypotheses

- Directional Hypotheses: These hypotheses specify the expected direction of the relationship (e.g., positive, negative, greater than, less than).

- Example: "Increased job stress will lead to decreased job satisfaction."

- Nondirectional Hypotheses: These hypotheses suggest a relationship or difference exists but do not specify the direction. They are used when there's no clear prior expectation or when research findings are conflicting.

○ Example: "There is a relationship between job stress and job satisfaction."

Null and Alternate Hypotheses

In statistical testing, hypotheses are often framed in terms of null and alternate hypotheses:

- Null Hypothesis (H 0) : This is a statement of no effect or no relationship. It is the hypothesis that researchers aim to reject.

○ Example: "There is no significant difference in job satisfaction between employees experiencing high job stress and those experiencing low job stress."

Math summary: This expression defines a null hypothesis for a statistical test. It states that the average value for the high stress group is equal to the average value for the low stress group.

• Alternate Hypothesis ( H A ): This is a statement that contradicts the null hypothesis, proposing that a relationship or difference does exist. This is typically the hypothesis the researcher expects to support.

○ Example: "Employees experiencing high job stress will have lower job satisfaction than employees experiencing low job stress." ( H A : mu high stress is less than mu low stress )

Hypothesis Testing Steps

1. State Hypotheses: Formulate the null H 0 and alternate H A hypotheses.

2. Choose Statistical Test: Select the appropriate statistical test based on the data type and research question (e.g., t-test, correlation).

3. Determine Significance Level: Set a significance level (alpha, alpha), commonly alpha equals 0.05.

4. Analyze Data: Conduct the statistical test.

5. Make Decision: Compare the test statistic's p-value to the significance level. If p is less than alpha, reject H 0 in favor of H A. Otherwise, fail to reject H 0.

Role of the Manager

Understanding theoretical frameworks and hypothesis development is crucial for managers to:

- Critically evaluate research reports and proposals.

- Understand how proposed solutions (independent variables) address problems (dependent variables).

• Recognize the nuances introduced by moderating and mediating variables.

- Make informed decisions based on research findings rather than hunches.

Example: Developing a Theoretical Framework and Hypotheses

Scenario: A manager of an online company believes that using avatars as virtual assistants will increase customer satisfaction and purchase intentions. This is because avatars are thought to enhance information value and the shopping experience. The manager also believes this positive effect is stronger for highly involved customers.

Problem Definition: To identify factors influencing customer satisfaction and purchase intentions in an online retail environment and to test the effectiveness of avatar-mediated communication.

Variables:

Independent Variables:

o Avatar presence (Yes/No, or type of avatar)

○ Perceived information value (e.g., a scale from low to high)

Perceived shopping experience pleasure (e.g., a scale from low to high)

Dependent Variables:

Customer satisfaction with the company

Purchase intentions

Moderating Variable: Customer involvement (e.g., low, medium, high)

Theoretical Framework:

1. Definitions:

- Avatar presence: The use of virtual characters to interact with customers on the website.

- Perceived information value: The extent to which customers believe the information provided by the avatar (or website through the avatar) is useful and relevant.

• Perceived shopping experience pleasure: The degree of enjoyment and positive emotion customers derive from their online shopping interaction.

- Customer satisfaction: A customer's overall positive or negative evaluation of their experience with the company.

- Purchase intentions: The likelihood that a customer will buy a product or service from the company.

2. Conceptual Model:

Diagram:

- Customer involvement: The level of personal relevance or interest a customer has in a product or shopping experience.

- Avatar presence is hypothesized to positively influence perceived information value and perceived shopping experience pleasure.

- Perceived information value and perceived shopping experience pleasure are hypothesized to positively influence customer satisfaction and purchase intentions.

- Customer involvement moderates the relationship between perceived information value and customer satisfaction/purchase intentions, such that the positive effect is stronger for highly involved customers.

Avatar Presence (4) --> Perceived Information Value (Mediating/Independent)

--> Perceived Shopping Experience Pleasure (Mediating/Independent)

Perceived Information Value (4) --> Customer Satisfaction D.V

Perceived Shopping Experience Pleasure (4) --> Customer Satisfaction D.V

Perceived Information Value (4) --> Purchase Intentions D.V

Perceived Shopping Experience Pleasure (4) --> Purchase Intentions D.V

Customer Involvement (Moderating) moderates the relationship between Perceived Information Value --> Customer Satisfaction/Purchase Intentions.

(Note: Perceived information value and pleasure could also be considered mediating variables if the primary focus is on how avatars lead to satisfaction/intentions through these factors.)

3. Theory: Social learning theory and theories of human-computer interaction suggest that anthropomorphic agents (like avatars) can enhance engagement by making interactions more relatable and enjoyable. Improved information delivery and a more pleasant experience are known drivers of satisfaction and purchase intent. High involvement means customers are more attentive to information and thus more likely to be influenced by its perceived value.

Hypotheses:

- Hypothesis 1: Avatar presence will be positively associated with perceived information value.

- H 2 : Avatar presence will be positively associated with perceived shopping experience pleasure.

• H 3: Perceived information value will be positively associated with customer satisfaction.

- H 4 : Perceived shopping experience pleasure will be positively associated with customer satisfaction.

- Hypothesis 5: Perceived information value will be positively associated with purchase intentions.

- H 6: Perceived shopping experience pleasure will be positively associated with purchase intentions.

- H 7 : Customer involvement will moderate the relationship between perceived information value and customer satisfaction, such that the relationship is stronger for high involvement customers.

- H 8 : Customer involvement will moderate the relationship between perceived information value and purchase intentions, such that the relationship is stronger for high involvement customers.

Elements of Research Design

Introduction to Research Design

A research design is the fundamental blueprint for a research project. It outlines the comprehensive plan for collecting, measuring, and analyzing data to effectively answer research questions and address the initial problem statement. Key components influencing research design include:

- Research Strategy: The overall plan for achieving research objectives (e.g., experiments, surveys, case studies).

- Extent of Researcher Interference: The degree to which the researcher manipulates or controls variables and settings.

- Study Setting: Whether the research is conducted in a natural (noncontrived) or artificial (contrived) environment.

- Unit of Analysis: The level of aggregation for data analysis (e.g., individuals, groups, organizations).

- Time Horizon: The temporal scope of the study (e.g., cross-sectional or longitudinal).

The quality of a research design hinges on the careful selection of alternatives for each component, considering the specific objectives, research questions, and practical constraints like data access, time, and budget.

Research Strategies

The choice of research strategy is guided by the research objectives, questions, the researcher's viewpoint on good research, and practical considerations.

Experiments

- Purpose: To study causal relationships between variables. They are less suitable for exploratory or descriptive questions.

- Method: The researcher manipulates an independent variable to observe its effect on a dependent variable.

- Example: A researcher might manipulate "reward systems" (independent variable) to study its effect on "productivity" (dependent variable).

- Simple Design: A two-group, post-test-only, randomized experiment involves a treatment group and a comparison group, with subjects randomly assigned.

- Limitations: Not always feasible in applied research where manipulating variables could have ethical or practical consequences (e.g., assigning customers to low service quality).

Survey Research

Purpose: To collect information from or about people to describe, compare, or explain their knowledge, attitudes, and behavior.

Application: Popular in business research for collecting both quantitative and qualitative data, often used in exploratory and descriptive research.

Common Topics: Consumer decision-making, customer satisfaction, job satisfaction, management information systems.

• Types:

One-time surveys.

Continuing surveys (to observe changes over time).

Instruments:

○ Self-administered questionnaires (paper or computer-based).

○ Interviews.

o Structured observation.

Ethnography

- Origin: Rooted in anthropology.

- Method: The researcher immerses themselves in the daily life of a culture or social group, closely observing, recording, and engaging to gain an "insider's point of view."

- Activities: Observing behavior, listening to conversations, asking questions.

• Related Concept: Participant observation is closely related, sometimes used interchangeably, but often considered a primary data collection method within ethnography.

• Data Collection: Observation, interviews, and questionnaires can be used.

Case Studies

Focus: Collecting in-depth information about a specific object, event, or activity (e.g., a particular business unit or organization).

Definition: An empirical investigation of a contemporary phenomenon within its real-life context, using multiple data collection methods.

• Data: Can yield both qualitative and quantitative data.

• Hypotheses: Hypotheses can be developed and tested, but a single unsubstantiated case can weaken support for a hypothesis.

Grounded Theory

- Purpose: To develop an inductively derived theory directly from the data.

• Key Tools: Theoretical sampling, coding, and constant comparison.

- Theoretical Sampling: Data collection is guided by emerging theory, with the analyst deciding what data to collect next and where to find it.

• Constant Comparison: Data are compared to other data, and then to the emerging theory. Discrepant and disconfirming cases are crucial for refining categories and theory.

Action Research

- Purpose: To effect planned changes in organizations, often initiated by consultants.

- Process: Begins with an identified problem, data are gathered for a tentative solution, the solution is implemented, and its effects are evaluated. This is an iterative cycle of problem identification, planning, acting, observing, and reflecting, continuing until the problem is resolved.

• Critical Elements: Sensible problem definition and creative data collection methods.

Extent of Researcher Interference

The degree to which a researcher interferes with the study setting influences whether the study is correlational or causal.

- Minimal Interference: Used in correlational (descriptive) studies conducted in natural environments where the researcher observes events as they normally occur. Example: Studying the relationship between perceived emotional support and stress among nurses using questionnaires.

- Moderate Interference: Involves manipulating variables to establish cause-and-effect in a natural setting (field experiment). Example: Manipulating the level of emotional support given to nurses in different hospital wards.

- Excessive Interference: Occurs when researchers create an artificial setting (lab experiment) to tightly control variables and establish causality beyond doubt. Example: Conducting a controlled experiment with medical students in separate rooms to isolate the effect of support on stress.

Study Setting

The environment where research is conducted can be either natural or artificial.

- Noncontrived Settings (Field Studies): Occur in the natural environment where events proceed normally. Exploratory and descriptive studies are typically conducted here with minimal researcher interference.

- Field Experiments: Causal studies conducted in the natural setting where the independent variable is manipulated, leading to moderate researcher interference. Example: Varying interest rates in different bank branches.

- Contrived Settings (Lab Experiments): Artificial environments created to control extraneous factors and study cause-and-effect relationships with excessive researcher interference. Example: Recruiting students for a controlled experiment on interest rates and savings.

Unit of Analysis

The unit of analysis determines the level at which data are aggregated for analysis.

• Individuals: Each person is a data source. Example: Studying employee motivation levels.

Dyads: Two-person interactions. Example: Supervisor-subordinate relationships.

Groups: Individual data aggregated to represent a group. Example: Comparing the effectiveness of different project teams.

• Organizations: Data aggregated at the organizational level. Example: Comparing the profitability of different company divisions.

• Cultures/Nations: Data aggregated at the national or cultural level. Example: Studying cross-cultural differences in consumer behavior.

The research question dictates the appropriate unit of analysis, influencing data collection methods, sample size, and variables.

Time Horizon

This refers to the temporal scope of the data collection.

- Cross-Sectional Studies (One-Shot): Data are gathered at a single point in time.

- Example: A survey to gauge interest in a new product.

- Pros: Relatively quick and cost-effective.

- o Cons: Cannot capture changes over time or establish causality as effectively.

- Longitudinal Studies: Data are collected at multiple points in time.

- Example: Tracking employee behavior before and after a management change.

- Pros: Can identify cause-and-effect relationships and track changes over time.

- o Cons: More time-consuming, costly, and require more effort.

- Note: Experimental designs are invariably longitudinal as they involve pre-and post-manipulation data collection.

Mixed Methods

This approach combines qualitative and quantitative research methods within a single study or series of studies.

- Purpose: To answer research questions that cannot be fully addressed by either approach alone.

- Benefits: Allows for the integration of inductive and deductive reasoning, uses diverse data types, and offers multiple perspectives.

• Challenges: Can complicate research design and requires clear presentation.

- Triangulation: A technique used in mixed methods research to increase confidence in findings by using multiple methods, data sources, researchers, or theories.

- o Method Triangulation: Using multiple data collection and analysis methods.

- Data Triangulation: Collecting data from various sources or at different times.

- Researcher Triangulation: Involving multiple researchers in data collection or analysis.

- ☐ Theory Triangulation: Using multiple theories or perspectives for interpretation.

Trade-offs and Compromises

Researchers often face constraints related to time, cost, and data access, which may necessitate settling for a less "ideal" research design. For instance, a researcher might opt for a cross-sectional study instead of a longitudinal one, or a field study over a full-blown experiment, due to resource limitations. These trade-offs between scientific rigor and practical considerations should be conscious and explicitly stated in the research report.

Managerial Implications

Understanding research design issues empowers managers to:

- Comprehend the researcher's approach and the rationale behind findings (e.g., small sample sizes in group studies).

- Make informed decisions about the desired level of research rigor based on the problem's gravity and available resources.

- Avoid misinterpreting correlations as causal relationships.

- Critically evaluate research proposals and reports.

Primary Data Collection: Interviews and Observation

Introduction to Primary Data Collection

Primary data collection involves gathering information directly from original sources for a specific study. In business research, this often means collecting data from people (employees, consumers, managers, investors, suppliers).

Key factors influencing the choice of data collection method include:

- Study objectives and research questions

• Available facilities and resources

• Required degree of accuracy

• Time span of the study

• Researcher's expertise

The primary data collection methods discussed are:

• Interviews (Chapter 7)

• Observation (Chapter 8)

• Questionnaires (Chapter 9)

• Experiments (Chapter 10)

Chapter 7: Interviews

An interview is a guided, purposeful conversation between two or more people.

Types of Interviews

Interviews can be classified by:

Structure

• Unstructured Interviews:

• No pre-planned sequence of questions.

• Purpose: To surface preliminary issues and determine what needs further investigation.

- Use when: The problem is vague, in the initial stages of exploration, or variables are not yet identified.

- Characteristics: Broad, open-ended questions are used. The interviewer follows leads from the respondent's answers.

• Example Questions:

• "Tell me about your unit, department, and the organization."

• "What do you like about working here? What aspects do you not like?"

• "If you could have a problem solved in your unit, what would that be?"

• Structured Interviews:

• Conducted when the information needed is known in advance.

• Content is prepared beforehand.

• Components:

• Introduction: Interviewer introduces self, purpose, assures confidentiality, asks permission to record.

- Logical Question Set: Warm-up questions (easy, non-threatening) followed by main questions.

• Probing Questions: Used when an answer is unclear, incomplete, or more depth is required.

• Probing Tactics: Silence, repeating the answer, "So what I hear you saying is…", "Could you tell me more about…", "Could you give an example?", "Anything else?".

Participants

• Individual (Personal) Interviews: One-on-one conversations.

• Group Interviews:

Interviews with multiple participants simultaneously.

• Focus Groups:

• Composition: 8 to 10 members + moderator.

• Selection: Based on familiarity with the topic.

• Purpose: Obtain impressions, interpretations, and opinions through discussion.

- Moderator Role: Steers discussion, ensures participation, resolves impasses.

• Data Nature: Qualitative only; not statistically representative.

• Uses: Exploratory studies, understanding why products fail or strategies are effective.

- Videoconferencing can enable groups at different locations.

• Expert Panels:

• Purpose: Elicit expert knowledge and opinion on a specific issue.

• Members: Independent specialists, scientists, policymakers, community stakeholders.

Mode

• Face-to-face: Direct, in-person interaction.

• Telephone: Conducted over the phone.

• Online/Computer-assisted:

- caty (Computer-Assisted Telephone Interviewing): Software prompts questions, computer dials, stores responses. Allows global reach.

- capy (Computer-Assisted Personal Interviewing): Handheld devices gather field survey data. Software prompts questions. Reduces recording errors.

- Key Advantages of C.A.I: Quick & accurate data gathering, faster analysis, low field costs, automatic tabulation.

- Disadvantages of C.A.I: Requires hardware/software investment, not all respondents have computer access.

Interviewer Training and Visual Aids

- Training Interviewers: Essential when multiple interviews are needed. Interviewers must be briefed on: starting, proceeding, motivating respondents, closing, note-taking, and coding. Good planning and supervision are key.

- Visual Aids: Pictures, drawings, cards shown to interviewees to indicate responses. Useful in marketing research (packaging, advertising), with children, or for difficult-to-articulate topics.

Advantages and Disadvantages of Interviews

Table summary: The table compares personal face-to-face data collection with telephone methods, highlighting that while personal interviews provide richer data and better rapport, they are more expensive and time-consuming compared to the greater speed, lower cost, and broader geographic reach of telephone surveys.

Tips for Interviewing

• Minimize Bias:

Bias can be introduced by the interviewer, interviewee, or situation.

- Interviewer Bias: Lack of trust/rapport, misinterpretation, encouraging/discouraging responses.

• Interviewee Bias: Providing expected answers, social desirability bias, reluctance.

- Situational Bias: Non-participation, trust levels, physical setting.

- Establish Credibility and Rapport: Be professional, enthusiastic, confident, sincere, pleasant, and non-evaluative. Assure confidentiality. Explain the purpose and how the respondent was chosen. Motivate respondents by explaining how their contribution will help.

• Questioning Technique:

- Funneling: Start with broad, open-ended questions and progressively narrow down to specific issues.

• Unbiased Questions: Avoid loaded questions or leading prompts.

- Clarifying Issues: Rephrase or restate to ensure understanding. Seek clarification when needed.

- Helping Respondent Think: Rephrase questions simply or use paired-choice questions if the respondent struggles to verbalize.

- Taking Notes: Take notes during or immediately after the interview. Avoid relying solely on memory.

• Recording: Obtain permission before recording interviews. Be aware that recording might introduce bias.

Chapter 8: Data Collection Methods: Observation

Observation is the planned watching, recording, analysis, and interpretation of behavior, actions, or events.

Purpose and Use of Observation

• Purpose: To collect descriptive data on behavior and actions without direct questioning.

• When Used: Best suited for non-self-report data.

• Examples: How workers perform jobs, how consumers use products, how businesses operate.

• Key Advantage: Rich data, uncontaminated by self-report bias.

Four Key Dimensions of Observation

1. Control:

- Controlled Observation: Carried out under carefully arranged conditions; the situation is manipulated or contrived by the researcher. Can be in a lab or field setting. Allows observation of differences in behavioral reactions to specific conditions.

- Uncontrolled Observation: No attempt to control or manipulate the situation. Events run their natural course in a natural setting. Advantage: Authentic behavior. Drawback: Difficult to untangle complex situations and identify causes.

2. Group Membership:

• Participant Observation:

I've researcher joins and participates in the group or organization under study to gain an insider's perspective.

• Levels of Participation:

• Passive: Researcher is present but not involved (e.g., sitting in a corner).

- Moderate: Occasional interaction; intermediate position (e.g., shadowing).

• Active: Researcher openly states role, engages in activities to understand practices.

• Complete: Researcher becomes a group member ("going native"); risks objectivity loss and ethical concerns.

- Non-participant Observation: The researcher observes from outside the group's visual horizon (e.g., via one-way mirror or camera). The researcher maintains a clear boundary and does not disrupt the setting.

3. Structure:

• Structured Observation: Uses a predetermined set of categories for observation. Generally quantitative. Formats are specifically designed. Used for hypothesis testing. Records duration, frequency, activities, emotions, communication.

- Unstructured Observation: Observer records practically everything observed, with no predefined focus at the start. Hallmark of qualitative research. Data is analyzed qualitatively. May lead to tentative hypotheses.

4. Concealment:

• Concealed Observation:

Subjects are unaware they are being studied.

• Advantage: Reduces reactivity, leading to more authentic behavior.

- Ethical Drawbacks: Raises concerns about informed consent, privacy, and confidentiality. Requires careful ethical assessment.

• Example: Researchers disguised as shoppers.

• Unconcealed Observation:

- Subjects know they are being observed.

- Drawback: Risk of reactivity, potentially upsetting the authenticity of behavior (e.g., the Hawthorne Effect).

Participant Observation in Detail

- Objective: To grasp the "native's point of view" and understand the world from an insider's perspective.

• Combines: Participation and observation (and sometimes interviews).

• Getting Started: Requires choosing a site, gaining permission, selecting key informants, and familiarizing oneself with the setting.

- Rapport: Crucial for establishing trust and obtaining reliable information. Built over time through active listening, reciprocity, and confidentiality.

• What to Observe:

- Descriptive Observation: Open to everything, collecting data to describe the setting, subjects, and events.

• Focused Observation: Concentrates on particular themes, emotions, actions.

• Selective Observation: Focuses on patterns and exceptions.

- Field Notes: Essential for capturing observations, conversations, and journal entries. Should be detailed, accurate, and objective. Notes are data and data analysis.

• Challenges: Requires commitment, tact, patience, observational skills, and the ability to separate participant and observer roles.

Structured Observation in Detail

- Nature: Focused, selectively observing predetermined phenomena. Data is fragmented into manageable pieces.

- Levels: Highly structured (precise, mutually exclusive categories) or semi-structured (detailed plan but less systematic collection).

• Examples: Mystery shoppers, using checklists and codes to monitor service performance.

- Coding Schemes:

- Crucial for structured observation. Predetermined categories for recording observations.

• Considerations for Construction:

• Focus: Clearly define what is to be observed.

• Objective: Categories should require little inference; use clear guidelines.

• Ease of Use: Simple to use in the field.

- Mutually Exclusive & Collectively Exhaustive: Categories should not overlap and must cover all possibilities.

• What to Measure:

• Frequency: How often an event occurs (e.g., using a simple checklist).

• Timing: When and in what order events occur, including duration (start and finish times).

• Ways to Code Events:

• Simple Checklist: Records frequency of events (e.g., tally marks).

- Sequence Record: Records frequency and order of events, providing insight into behavioral sequences.

• Sequence Record on Timescale: Adds time intervals, showing duration and pacing.

• Quality Criteria:

• Reliability: Consistency of results among observers or across time.

• Validity: Accuracy – observations truly record the behavior of interest.

Advantages and Disadvantages of Observation

• Advantages:

• Directness: Gathers behavioral data without asking questions.

• Rich Data: Can observe environmental factors alongside behavior.

• Access to Certain Groups: Useful for observing children or busy executives.

- Reliability: Data can be more reliable and free from respondent bias when events occur naturally.

• Disadvantages:

- Reactivity: Observed subjects may behave differently (threat to validity). This diminishes over time.

• Observer Bias: Researcher's perspective can be biased, especially in participant observation ("going native"). Can lead to recording/interpretation errors.

- Time-Consuming: Can be slow, tedious, and expensive, especially for participant observation.

- Limited Scope: Cannot capture cognitive thought processes or underlying reasons for behavior. Often complements other methods.

Administering Questionnaires What is a Questionnaire?

A questionnaire is a preformulated written set of questions designed to collect quantitative data. Respondents record their answers, usually within defined alternatives.

Functions

• Designed to collect large numbers of quantitative data.

Common in survey research, case study research, and experimental designs.

Types of Administration

Administered personally.

• Distributed electronically.

• Mailed to respondents.

Advantages

• Less expensive and time-consuming than interviews or observation.

Disadvantages

• Higher chance of nonresponse and nonresponse error.

Types of Questionnaires

Personally Administered Questionnaires

• Description: Used when the survey is confined to a local area.

• Advantages:

• Researcher can collect completed responses quickly.

• Respondents' doubts can be clarified on the spot.

• Researcher can motivate respondents for frank answers.

More efficient than interviewing (less expensive, less time, less skill required).

• Disadvantages:

• Researcher may introduce bias by explaining questions differently.

• Takes more time and effort compared to other types.

Mail Questionnaires

- Description: Self-administered paper-and-pencil questionnaires sent via mail. Historically a backbone of business research, now often considered obsolete due to electronic methods.

Electronic and Online Questionnaires

• Description: Created as "web forms" with databases for answers and statistical software for analysis.

• Advantages:

• Access to groups and individuals difficult to reach otherwise.

• Wide geographical area can be covered.

• Respondents can complete at their convenience, pace, and location.

• Automatic processing saves costs, time, and energy.

• Disadvantages:

• Sampling problems: representativeness and generalizability issues due to self-selection.

• Extremely low response rates (30% is considered acceptable/exceptional).

• Invitations via social networks or email can be perceived as rude.

• Doubts of respondents cannot be clarified on the spot.

Improving Response Rates for Electronic Questionnaires

• Send follow-up mails.

• Keep the questionnaire brief.

• Notify respondents in advance.

• Be from a reputed research organization.

• Offer a small monetary incentive.

Questionnaire Design Principles

Sound design focuses on three areas:

1. The wording of the questions.

2. The planning of measurement issues (categorization, scaling, coding).

3. The general appearance of the questionnaire.

Principles of Wording

Content and Purpose of Questions

• Subjective Feelings (e.g., satisfaction):

Questions should tap the dimensions of the concept.

• Example: "How satisfied are you with our product/service?"

• Objective Facts (e.g., educational levels):

A single, direct question with scaled categories is preferred.

Example: "What is the highest level of education you have completed?" with options like "High School Diploma/G.E.D "Associate's Degree," "Bachelor's Degree," etcetera

Language and Wording

• The language should approximate the respondents' level of understanding.

- Avoid jargon or complex terms that may not be understood.

• Consider cultural nuances in vocabulary and idioms.

Type and Form of Questions

• Open-ended versus Closed Questions:

• Open-ended: Allows respondents to answer in their own words (e.g., "What do you like most about your job?"). Useful for exploratory insights but harder to analyze.

• Closed: Provides a set of alternatives for the respondent to choose from (e.g., Likert scales, multiple-choice). Easier to code and analyze, but alternatives must be mutually exclusive and collectively exhaustive.

• Positively and Negatively Worded Questions:

Interspersing these can minimize mechanical responses (e.g., always picking the highest score).

- Example of positive: "I feel I have been able to accomplish a number of different things in my job."

- Example of negative: "I do not feel I am very effective in my job."

• Double-barreled Questions:

Avoid questions with multiple parts that could elicit different responses.

- Bad Example: "Do you think there is a good market for the product and that it will sell well?"

• Better: Ask two separate questions.

• Ambiguous Questions:

Questions that can be interpreted in multiple ways should be avoided.

- Example: "To what extent would you say you are happy?" (Happy about what? Work? Life?)

- Recall-Dependent Questions: Questions requiring respondents to recall specific past events can be prone to error. Check records if possible.

Leading Questions:

Questions phrased to suggest a desired answer should be avoided.

Bad Example: "Don't you think that employees should be given good pay rises?"

• Better: "To what extent do you agree that employees should be given higher pay rises?"

• Loaded Questions:

Questions phrased with emotionally charged language can create bias.

- Example: "To what extent do you think management is likely to be vindictive if the union decides to go on strike?"

• Social Desirability:

Questions should not be worded to elicit responses that are socially acceptable rather than truthful.

- Example: "Do you think that older people should be laid off?" (Likely to get a "no" due to social pressure.)

- Better: "There are advantages and disadvantages to retaining senior citizens in the workforce. To what extent do you think companies should continue to keep the elderly on their payroll?"

- Length of Questions: Keep questions short, ideally not exceeding 20 words or one full line of print.

Sequencing of Questions

- Funnel Approach: Start with general questions and move to more specific ones. Begin with easy questions and progress to more difficult ones.

- Questions about the same concept should generally be placed far apart to avoid ordering effects or respondents feeling repetitive.

Classification Data (Personal/Demographic Information)

• Includes age, education, marital status, income, etcetera

- Avoid asking for names unless absolutely necessary, and explain the procedure for maintaining anonymity.

• Placement:

• Beginning: Can help with psychological identification and commitment.

- End: Respondents may be more convinced of the survey's legitimacy and willing to share sensitive information.

- Sensitive Questions (e.g., income): Best placed at the very end. Provide response ranges rather than exact figures.

- Even if not directly in the theoretical framework, demographic data are needed to describe sample characteristics.

Principles of Measurement

• Categorization: Grouping responses into meaningful categories.

• Coding: Assigning numerical values to categories for analysis.

• Scales and Scaling:

Using appropriate scales (nominal, ordinal, interval, ratio) to measure variables.

- Nominal Scale: Used for categorical data where groups are meaningful (e.g., gender, department).

- Ordinal Scale: Used for ranking preferences or order (e.g., ranking brands, satisfaction levels from low to high).

• Reliability: The consistency and stability of a measure.

- Validity: The extent to which a measure accurately measures the concept it intends to measure.

General Appearance of the Questionnaire

Introduction

• Identifies the researcher.

Clarifies the survey's purpose.

• Establishes rapport and motivates respondents.

• Provides assurance of confidentiality.

• Ends with a thank you.

Organization, Instructions, and Alignment

• Organize questions logically into sections.

• Provide clear instructions for completing each section.

- Align questions neatly to minimize respondent effort and eye strain.

• Justify sensitive questions by explaining their contribution to knowledge.

• Include an open-ended question at the end for general comments.

• End with sincere thanks.

Pretesting of Structured Questions

- Purpose: To test the appropriateness and comprehension of questions using a small group of respondents.

• Process: Debrief pretest participants to gather feedback.

• Benefit: Rectifies inadequacies before full administration, reducing bias.

International Dimensions of Surveys

Cultural Sensitivity

- Be aware of cultural differences that may affect responses.

Translation Issues

• Vocabulary Equivalence: Ensure translated words have the same meaning.

• Idiomatic Equivalence: Account for idioms that do not translate directly.

• Conceptual Equivalence: Understand that the meaning of concepts can differ across cultures.

• Process:

1. Translate the instrument by a local expert.

2. Back-translate the instrument to the original language by a bilingual individual.

Example: Pepsi's slogan "Come alive with the Pepsi generation" translated to Chinese meant "Pepsi brings your ancestors from the grave."

Cross-Cultural Data Collection Issues

• Response Equivalence: Ensure uniform data collection procedures across cultures.

- Timing of Data Collection: Complete data collection within comparable timeframes across countries.

- Status of Data Collector: Be mindful of how the perceived status of the researcher might influence responses in different cultural contexts. Collaboration with local researchers is often beneficial.

Review of Data Collection Methods

Interviews

• Advantages: Rich data, establish rapport, explore complex issues.

• Disadvantages: Potential for interviewer bias, expensive for large samples.

• Best Used: Exploratory stages, understanding complex issues.

Observation

• Advantages: Comprehend complex issues directly, data not self-reported.

• Disadvantages: Expensive, time-consuming, potential for observer bias.

• Best Used: Research requiring non-self-report descriptive data, understanding behaviors.

Questionnaires

• Advantages: Efficient for large samples, wide geographical reach, cost-effective.

- Disadvantages: Nonresponse bias, lack of clarification for respondents, potential for misunderstanding.

- Best Used: Collecting data on a large scale, structured questions, geographically dispersed samples.

Multimethods and Multisources of Data Collection

- Rationale: All data collection methods have biases; using multiple methods and sources can increase research rigor.

- Benefit: Correlated results from different methods/sources increase confidence in data quality. Discrepant results suggest potential bias.

• Example: The Delphi Technique involves iterative rounds of questionnaires to experts to reach a consensus.

Managerial Implications

• Understanding data collection methods helps managers evaluate approaches and collaborate effectively with researchers.

- Managers can influence the sophistication and focus of data collection.

- Managers can develop sensitivity to question wording, cultural variations, and ethical considerations.

Measurement of Variables: Operational Definition

Introduction to Measurement

Measurement is the process of assigning numbers or symbols to characteristics (attributes) of objects based on a predefined set of rules.

Key Components of Measurement:

• Objects: These are the entities being studied (e.g., companies, individuals, products).

- Characteristics/Attributes: These are the specific properties of the objects being measured (e.g., organizational effectiveness, motivation, price, quality).

- Judge: An individual with the necessary knowledge and skills to assess the characteristic. In many cases, the object itself can serve as the judge (e.g., self-reported enjoyment). However, for abstract or subjective attributes, an external judge might be needed.

Types of Attributes and Measurement Challenges

Attributes can be broadly categorized into two types:

• Physically Measurable Attributes: These are attributes that can be measured objectively using calibrated instruments (e.g., length with a ruler, weight with scales, demographic data like age or marital status).

- Abstract and Subjective Attributes: These attributes are more difficult to measure as they are internal, psychological, or perceptual (e.g., achievement motivation, shopping enjoyment, organizational commitment, marketing orientation). Simple questions often do not suffice for these.

Operational Definition (Operationalization)

Operationalization is the process of reducing abstract concepts to observable behaviors or characteristics, making them measurable. It involves translating nebulous variables into tangible and quantifiable terms.

Steps in Operationalization:

1. Define the Construct: Clearly articulate the meaning of the abstract concept.

2. Determine the Content of the Measure: Develop an instrument (one or more questions/items) that captures the essence of the construct. This involves identifying observable behaviors or characteristics associated with the construct.

3. Choose a Response Format: Select a scale (e.g., Likert scale, semantic differential scale) for respondents to indicate their answers.

4. Assess Validity and Reliability: Evaluate the quality of the measurement instrument.

Operationalizing Abstract Concepts:

Example: Thirst

• Abstract concept: Thirst.

• Observable behavior: Drinking fluids.

- Measurement: The quantity of fluids consumed to quench thirst can serve as a measure of thirst level.

• Example: Need for Cognition

• Construct: The tendency to engage in and enjoy thinking.

- Observable behaviors/characteristics: Preference for complex problems, satisfaction in deep thinking, enjoyment of tasks requiring problem-solving.

- Measurement: A scale with items like "I really enjoy a task that involves coming up with new solutions to problems" or "I would prefer a task that is intellectual, difficult, and important to one that is somewhat important but does not require much thought."

Dimensions and Elements of Constructs

- Uni-dimensional Constructs: These have a single primary component (e.g., thirst, need for cognition). A valid measure should adequately represent this single domain.

- Multi-dimensional Constructs: These have multiple components or dimensions (e.g., aggression, which can include verbal and physical aggression). A valid measure must include items that capture all relevant dimensions.

Achievement Motivation Example:

• Construct: Achievement Motivation (drive to succeed, attain goals).

• Dimensions:

1. Driven by work.

2. Difficulty relaxing.

3. Preference for working alone.

4. Preference for challenging jobs (but not excessively so).

5. Desire for feedback.

• Elements (Observable Behaviors):

- Driven by work: Spending many hours working, persevering through setbacks, reluctance to take time off.

- Difficulty relaxing: Thinking about work at home, lack of hobbies, neglecting personal matters for work.

- Preference for working alone: Discomfort with slow or inefficient colleagues, preference for independent work.

- Preference for challenging jobs: Opting for challenging over routine tasks, preferring moderate over overwhelming challenges.

• Desire for feedback: Actively seeking feedback from superiors, colleagues, and subordinates; impatience for immediate feedback.

What Operationalization Is Not

Operationalization should focus on the observable characteristics of a concept, not its correlates, antecedents, or consequences.

- Correlates: For example, success in performance is a correlate of achievement motivation, not a measure of it. A highly motivated person might fail due to external factors. Measuring success would measure performance, not motivation itself.

• Antecedents: Factors that lead to the concept.

• Consequences: Outcomes resulting from the concept.

A valid operationalization ensures that the measurement tool captures the intended construct without measuring something else.

Types of Scales

Scales are used to quantify responses. They differ in the level of information they provide.

- Nominal Scale: Categorizes data into mutually exclusive and collectively exhaustive groups (e.g., nationality: American, Japanese, Chinese). No order or magnitude is implied.

- Ordinal Scale: Rank-orders categories in a meaningful way (e.g., ranking job characteristics by importance: 1st, 2nd, 3rd). The distance between ranks is not necessarily equal.

- Interval Scale: Has equal distances between points, allowing for comparison of differences (e.g., a 7-point Likert scale where the difference between 1 and 2 is the same as between 4 and 5). However, there is no true zero point.

- Ratio Scale: Possesses all properties of interval scales plus a true, absolute zero point, allowing for proportion comparisons (e.g., number of children, number of retail outlets, elapsed time).

Scaling Techniques in Business Research

These techniques help in designing measurement instruments.

Rating Scales (Each object scaled independently):

• Dichotomous Scale: Two response options (e.g., Yes/No, Male/Female).

- Category Scale: Multiple discrete categories (e.g., geographic regions: East London, South London).

- Semantic Differential Scale: Uses bipolar adjectives to measure attitudes (e.g., Responsive <-> Unresponsive).

• Numerical Scale: A numerical scale with anchors (e.g., 0 to 10).

- Itemized Rating Scale: Predefined points with labels (e.g., Very Unlikely, Unlikely, Neither Unlikely Nor Likely, Likely, Very Likely). Can be balanced (with a neutral point) or unbalanced.

- Likert Scale: A specific type of itemized rating scale measuring agreement/disagreement (e.g., Strongly Disagree to Strongly Agree).

- Fixed or Constant Sum Scale: Respondents allocate a fixed sum of points across items to indicate relative importance.

• Stapel Scale: A single adjective scale with numerical points, often ranging from +3 to -3.

• Graphic Rating Scale: A continuous scale (e.g., a line) where respondents mark their response.

• Consensus Scale: Items are selected by a panel of judges to measure a concept.

Ranking Scales (Comparisons among objects):

• Paired Comparison: Respondents choose between two items at a time.

• Forced Choice: Respondents select from a set of descriptive statements that are matched on some characteristic (e.g., equally desirable or undesirable).

- Comparative Scale: Items are compared against a benchmark (e.g., "More useful," "About the same," "Less useful").

International Dimensions of Operationalization

When conducting cross-cultural research, it's crucial to recognize that concepts can have different meanings and connotations across cultures. Researchers should collaborate with local scholars to ensure accurate operationalization.

Summary of Key Concepts

• Measurement: Assigning numbers/symbols to attributes of objects.

- Operationalization: Making abstract concepts measurable by defining them in terms of observable behaviors or characteristics. Necessary for subjective variables.

- Dimensions and Elements: Constructs can have multiple dimensions, each requiring specific elements (observable behaviors) for measurement.

- Valid Operationalization: Captures the intended construct and avoids measuring correlates or other concepts.

• Scales: Tools used to quantify responses (nominal, ordinal, interval, ratio).

• Scaling Techniques: Various methods for designing measurement instruments (rating scales, ranking scales).

Goodness of Measures and Sampling

Goodness of Measures

To ensure the quality of data collected, it's crucial to evaluate the "goodness" of the measures used. This involves assessing if the instrument accurately measures what it's intended to measure (validity) and if it consistently measures it (reliability).

Item Analysis

Item analysis is a preliminary step to assess the quality of individual items within an instrument. It examines each item's ability to discriminate between individuals with high total scores and those with low total scores. This is typically done by calculating t-values to detect significant differences between these groups. Items with high t-values are considered good discriminators and are included in the final instrument.

Validity

Validity refers to the extent to which an instrument measures the concept it is designed to measure. There are several types of validity:

• Content Validity: Ensures that the measure includes an adequate and representative set of items that cover all important dimensions and elements of the concept. It is often assessed by a panel of judges.

- o Face Validity: A subset of content validity where, on the surface, the items appear to measure the intended concept.

- Criterion-Related Validity: Assesses how well the measure differentiates individuals based on a criterion it is expected to predict.

◦ Concurrent Validity: The scale differentiates individuals who are known to be different at the present time.

- Predictive Validity: The scale accurately predicts a future criterion.

• Construct Validity: Evaluates how well the measure aligns with the underlying theory and the construct it aims to measure.

- Convergent Validity: Scores from the measure are highly correlated with scores from other measures of the same construct.

- Discriminant Validity: Scores from the measure have a low correlation (or no correlation) with scores from measures of different, theoretically unrelated constructs.

Reliability

Reliability indicates the extent to which a measure is free from random error, ensuring consistent measurement over time and across different items.

• Stability of Measures: The ability of a measure to remain the same over time.

- Test-Retest Reliability: Assessed by administering the same measure to the same respondents on two different occasions and correlating the scores.

- Parallel-Form Reliability: Assessed by correlating responses on two comparable sets of measures that tap the same construct.

• Internal Consistency of Measures: Assesses the homogeneity of items within a measure, meaning they all tap the same underlying construct.

- Interitem Consistency Reliability: Measures the consistency of respondents' answers across all items in a measure. Common tests include Cronbach's coefficient alpha (for multi-point scales) and Kuder-Richardson formulas (for dichotomous items).

- Split-Half Reliability: Reflects the correlation between two halves of an instrument.

Key Concepts Summary

• Goodness of Data: Encompasses both reliability and validity.

• Validity: Are we measuring the right thing?

° Content Validity (Logical validity)

Criterion-Related Validity (Concurrent, Predictive)

o Construct Validity (Convergent, Discriminant)

• Reliability: Are we measuring consistently?

◦ Stability (Test-Retest, Parallel-Form)

Consistency (Interitem, Split-Half)

Sampling

Sampling is the process of selecting a subset of individuals, objects, or events from a larger population to represent that population in a study.

Why Use Sampling?

- Impracticality: It's often impossible or impractical to collect data from every member of a large population.

• Cost and Time: Sampling saves significant time, money, and human resources.

• Efficiency: Reduces fatigue and potential for errors compared to census-level data collection.

- Destructive Sampling: In some cases (e.g., testing product lifespan), sampling is necessary to leave products for sale.

Key Sampling Concepts

• Population: The entire group of interest that the researcher wishes to study.

• Element: A single member of the population.

• Sample: A subset of the population from which data is collected.

• Sampling Unit: The element or set of elements available for selection at any stage of the sampling process.

Subject: A single member of the sample.

Sample Data versus Population Values

• Statistics: Numerical values calculated from sample data (e.g., sample mean x bar, sample standard deviation S). These are used to estimate population parameters.

• Parameters: Numerical values describing the population (e.g., population mean mu, population standard deviation sigma).

The Sampling Process

1. Define the Population: Clearly specify the target population in terms of elements, geographical boundaries, and time.

2. Determine the Sample Frame: Obtain a physical representation of the population (e.g., a list, directory) from which the sample will be drawn. Errors can occur if the frame doesn't perfectly match the population (coverage error).

3. Determine the Sampling Design: Choose between probability or nonprobability sampling methods.

4. Determine the Appropriate Sample Size: Decide how many elements are needed for the study.

5. Execute the Sampling Process: Select the sample according to the chosen design and size.

Sampling Designs

Probability Sampling

In probability sampling, every element in the population has a known, nonzero chance of being selected. This allows for generalization of findings to the population.

• Unrestricted (Simple Random Sampling): Every element has an equal chance of selection.

- Advantages: Least bias, most generalizable.

- Disadvantages: Can be cumbersome, requires an updated sampling frame, may not be efficient for stratified populations.

• Restricted (Complex Probability Sampling): More efficient or tailored designs.

- Systematic Sampling: Select every nth element after a random start.

- Advantages: Easy to implement if a frame is available.

■ Disadvantages: Potential for systematic bias if there's a pattern in the frame.

- Stratified Random Sampling: Divide the population into strata (subgroups) and randomly sample from each.

- Proportionate: Sample size from each stratum is proportional to its size in the population.

■ Disproportionate: Sample size from each stratum is not proportional, often used for small strata or strata with high variability.

- Advantages: Most efficient, ensures representation of all subgroups, provides detailed information on strata.

■ Disadvantages: Requires meaningful stratification and a frame for each stratum.

- Cluster Sampling: Divide the population into clusters (natural aggregates), randomly select clusters, and sample elements within those clusters.

- Advantages: Cost-effective, useful when a sampling frame is unavailable.

■ Disadvantages: Less reliable and generalizable due to potential homogeneity within clusters.

- Area Sampling: A form of cluster sampling where clusters are geographic areas.

- Double Sampling: Collect preliminary data from an initial sample, then collect more detailed data from a subsample of that initial sample.

- Advantages: Provides more detailed information at a lower cost.

Nonprobability Sampling

In nonprobability sampling, elements do not have a known or predetermined chance of selection. Findings are not generalizable to the population with statistical confidence.

• Convenience Sampling: Selects individuals who are readily available and easy to access.

Advantages: Quick, inexpensive, useful for exploratory research.

Disadvantages: Not generalizable at all.

• Purposive Sampling: Subjects are selected based on specific criteria or expertise.

• Judgment Sampling: Researcher uses their judgment to select subjects who are best positioned to provide information.

Advantages: Useful when specific expertise is required.

Disadvantages: Subjective, limited generalizability.

Quota Sampling: A predetermined number of subjects from different subgroups are sampled, but on a convenience basis.

Advantages: Ensures representation of subgroups, useful when minority groups are of interest.

■ Disadvantages: Not generalizable, selection within quotas is non-random.

Precision and Confidence

• Precision: Refers to how close the sample estimate is to the true population characteristic. A narrower confidence interval indicates greater precision. It's related to the standard error ( S X ), which is inversely related to the square root of the sample size ( square root of n ).

Math summary: This expression calculates the standard error of a sample. It divides the sample standard deviation by the square root of the sample size to determine the precision of the estimate.

• Confidence: Refers to the certainty that the sample estimate will fall within a specific range (confidence interval) that captures the true population parameter. Often expressed as a percentage (e.g., 95% confidence level, p less than or equal to 0.05).

- Trade-off: For a fixed sample size, increasing confidence requires decreasing precision (widening the interval), and vice versa. To increase both, the sample size must be increased.

Determining Sample Size

Factors influencing sample size include:

• Research objective

• Desired level of precision (margin of error)

• Desired confidence level

• Population variability

• Cost and time constraints

• Population size (for finite populations, a correction factor may be used)

A common approach is to use tables (e.g., Krejcie & Morgan) or formulas based on desired precision, confidence, and estimated population variability.

Sampling in Qualitative Research

Qualitative research often uses nonprobability sampling (especially purposive sampling) because the goal is not statistical generalization but in-depth understanding. Theoretical sampling is used in grounded theory, where sampling continues until theoretical saturation is reached.

Managerial Implications

Understanding sampling helps managers interpret research findings, assess the generalizability and risks associated with recommendations, and make informed decisions about research investments.

Qualitative Data Analysis Introduction to Qualitative Data

Qualitative data is data that is in the form of words. It can be collected from various sources, including:

• Interview notes

• Transcripts of focus groups

• Answers to open-ended questions

• Transcriptions of video recordings

• Accounts of experiences with a product on the internet

• News articles

Steps in Qualitative Data Analysis

Qualitative data analysis typically involves three main steps:

1. Data Reduction: This is the process of selecting, coding, and categorizing the data.

2. Data Display: This involves presenting the reduced data in an organized and condensed manner.

3. Drawing of Conclusions: This is the final analytical step where research questions are answered by interpreting patterns and relationships found in the data.

It is important to note that qualitative data analysis is an iterative process, not a linear one. This means that steps may be revisited and refined as the analysis progresses.

Data Reduction

Data reduction is achieved through coding and categorization.

- Coding:

This is an analytic process where qualitative data is reduced, rearranged, and integrated to form theory.

- A code is a label assigned to a unit of text, which is later grouped into categories.

- A coding unit can be words, sentences, paragraphs, or themes.

• Categorization:

This is the process of organizing, arranging, and classifying coding units.

- Codes and categories can be developed either inductively (from the data itself) or deductively (based on existing theory).

Example of Coding and Categorization:

Consider the critical incident: "After the meal I asked for the check. The waitress nodded and I expected to get the check. After three cigarettes there was still no check. I looked around and saw that the waitress was having a lively conversation with the bartender."

This incident can be coded into two themes:

1. "Delivery promises" (that were broken): This captures the expectation of receiving the check promptly after being told it would come.

2. "Personal attention" (that was not provided): This highlights the waitress's inattention to the customer due to engaging in conversation.

These codes are then grouped into broader categories. For instance, these two codes might fall under a larger category of "Service Failures."

Data Display

Data display involves presenting the reduced data in an organized and condensed format to help identify patterns and relationships. Common forms of data display include:

• Charts

• Matrices

• Diagrams

• Graphs

Frequently mentioned phrases

• Drawings

The purpose of data display is to facilitate the drawing of conclusions by making the data more understandable and revealing underlying patterns.

Example of Data Display (Conceptual):

Imagine a matrix where rows represent customer reviews and columns represent categories like "Product Quality", "Price," and "Customer Service." Each cell would indicate the presence of that category within the review and potentially a sentiment score.

Table summary: The data shows a correlation between customer sentiment and the specific aspects of the product being reviewed, where high sentiment is linked to product quality despite price concerns, while low sentiment is driven by poor customer service.

Table summary: The table contains a customer comment indicating that competing services offer comparable quality with superior customer support.

Drawing Conclusions

This is the final stage where the researcher interprets the findings from the reduced and displayed data to answer research questions. This involves identifying themes, explaining patterns, and making comparisons.

Example of Drawing Conclusions:

Based on the "Instigations of Customer Anger" study, conclusions were drawn about seven categories of events that instigate anger: unreliability, inaccessibility, company policies, insensitive behavior, impolite behavior, outcome failures, and inadequate responses to service failures. The study concluded that while each event could be a sufficient cause of anger, compound incidents suggest interactions between these critical behaviors.

Reliability and Validity in Qualitative Research

Reliability and validity in qualitative research have different meanings compared to quantitative research.

Reliability

Reliability in qualitative research refers to the consistency of the findings. Key aspects include:

- Category Reliability: The ability of analysts to formulate categories and present them to judges who agree on whether specific data items belong to a category. This requires clear category definitions.

- Interjudge Reliability: The degree of consistency between different coders processing the same data. A commonly used measure is the percentage of coding agreements, with rates at or above 80% considered satisfactory.

A balance must be struck between category reliability and the relevance of categories. Overly broad categories might be reliable but lack practical relevance.

Validity

Validity in qualitative research refers to the extent to which the research results are accurate and can be generalized.

• Internal Validity: The accuracy with which the research results represent the collected data.

• External Validity: The extent to which the results can be generalized or transferred to other contexts or settings.

Methods for achieving validity include:

• Supporting generalizations with counts of events.

- Ensuring representativeness of cases and including deviant cases (those that contradict the theory).

• Triangulation: Using multiple data sources, methods, or researchers to corroborate findings.

- Providing in-depth descriptions of the research project to allow others to judge the transferability of findings.

Other Methods of Qualitative Data Collection and Analysis

Content Analysis

- A systematic method for evaluating the symbolic content of recorded communications (e.g., newspapers, websites, advertisements).

- Used to analyze large amounts of text, identifying properties like words, concepts, characters, themes, or sentences.

• Conceptual Analysis: Establishes the existence and frequency of concepts.

• Relational Analysis: Examines the relationships among concepts.

Narrative Analysis

- Focuses on eliciting and scrutinizing stories people tell about themselves and their implications.

- Often collected through interviews designed to encourage participants to describe incidents within their life history.

- Emphasizes process and temporal order, examining antecedents and consequences of events.

Analytic Induction

- A strategy for seeking universal explanations of phenomena.

- Involves collecting qualitative data until no cases inconsistent with a hypothetical explanation are found.

• The process includes:

1. Rough definition of a problem.

2. Hypothetical explanation.

3. Examination of cases.

4. Redefining the hypothesis or excluding deviant cases if inconsistencies arise.

- This method uses inductive reasoning, allowing for hypothesis modification throughout the research process.

Big Data

• Refers to the exponential growth and availability of data from digital sources.

• Characterized by:

• Volume: The sheer amount of data.

Variety: The many different types of data (structured, unstructured, semi-structured like text, images, videos).

• Velocity: The pace at which data becomes available.

• An additional characteristic, veracity, refers to the biases and noise often present in big data.

Big data holds significant potential for organizations and managers but also presents challenges in management, processing, and analysis.

Ethics in Research Ethical Conduct Overview

Ethical conduct is crucial throughout the entire research process, involving the researcher, organizational gatekeepers, research sponsors, and research participants. Key ethical issues include:

• Simultaneous Submission: Submitting the same manuscript to multiple journals at once.

- Duplicate Submission: Similar to simultaneous submission, this involves submitting already published work.

• No Informed Consent: Failing to obtain proper consent from participants.

• Salami Slicing: Dividing a single research project into multiple small publications.

- Non-Disclosure of Safety Procedures: Not informing participants about potential risks.

• No Permission for Data/Information Usage: Using data without explicit permission.

- Conflicts of Interest: Situations where personal interests could compromise professional judgment.

• Authorship Issues: Disputes over who should be credited as an author and in what order.

• Plagiarism: Presenting someone else's work or ideas as your own.

• Data Falsification: Manipulating research data to support desired outcomes.

• Copyright Infringement: Using copyrighted material without permission.

• Data Fabrication: Inventing data to present as genuine

- Image Manipulation: Altering images in a way that misrepresents the original data.

Ethical Issues Throughout the Research Process

Ethical considerations are present at every stage of research:

• Formulating and Clarifying Research Topic: Ensuring the topic is ethically sound and doesn't inherently lead to ethical breaches.

• Designing Research and Gaining Access:

Most ethical issues should be anticipated and addressed during the design phase.

• Do not pressure or coerce intended participants to grant access.

• Avoid offering inducements beyond reimbursement for expenses or time.

• Assess the acceptability of risks to participants.

• Inform participants of their right to withdraw at any time.

• Approach participants in a way that avoids causing harm or distress.

• For secondary data, obtain consent or ensure anonymity.

• Collecting Data:

• Respect participants' consent and their right to withdraw or decline specific questions.

• Avoid deceit and renegotiate access if research aims change.

- Maintain objectivity by collecting data accurately and without subjective selectivity.

• Processing and Storing Data:

• Maintain objectivity.

• Ensure confidentiality and anonymity.

• Observe agreed-upon consent terms.

- Use and secure personal data appropriately.

• Analysing Data and Reporting Findings:

• Maintain objectivity.

• Recognize and declare conflicting interests.

• Ensure confidentiality and anonymity.

• Observe agreed-upon consent terms.

• Verify data and ensure the right to quality research for participants.

• Respect the researcher's right to privacy and safety.

• Avoid causing harm.

• Consider the need for debriefing.

Consent

Consent is a complex issue in research. It involves more than just agreeing to participate; it extends to how data will be used.

- Scope of Consent: Participants may agree to participate but not necessarily to the full use, storage, and reporting of their data without clarification.

• Types of Consent:

- Inferred Consent: The researcher assumes consent for data analysis, use, storage, and reporting based on participation without explicit clarification.

- Informed Consent: Participants receive sufficient information, have opportunities to ask questions, are given time to consider without pressure, and freely make a considered decision about participation.

• Deception: Involves misleading participants about the research purpose, sponsorship, or potential commercial use of data.

Consent and Participant Information

- Lack of Consent: Occurs when participants lack knowledge or when researchers use deception.

- Inferred Consent: Can arise when participants don't fully understand their rights, and the researcher infers consent about data use from access or questionnaire return.

- Informed Consent: Given freely and based on full information about participation, rights, and data use.

A Participant Information Sheet should include:

• The nature of the research.

• Requirements and implications of taking part.

• Participants' rights.

• How data will be analyzed, reported, and stored.

• Contact information for concerns.

Obtaining Participant Consent

• Provide a participant information sheet (in person, by mail, email, or online).

• For anonymous questionnaires, the return of a completed questionnaire can be taken as

- consent (with an information sheet included).

- For interviews, a signed consent form by both parties is recommended, including consent for photography or videorecording if applicable.

• Reinforce prior consent at the data collection stage.

• Obtain informed consent from organizational gatekeepers for access.

• Be realistic about benefits offered to organizations for access.

Ethical Issues During Data Collection

- Participant Consent: Participants have the right to withdraw or decline specific parts of the research.

• Deceit: Changing research aims without renegotiating access.

- Objectivity: Collecting data accurately and fully without subjective selectivity.

Confidentiality and Anonymity

Ensuring confidentiality and anonymity is vital.

- Anonymising Quantitative Data: Often straightforward through aggregation or removal of key variables.

- Anonymising Qualitative Data: Can be challenging due to the risk of indirect identification (e.g., participants inferring claims of others). Internet and email data collection pose additional risks (e.g., message forwarding).

• Always ensure that research practices do not cause harm.

Ethical Issues in Interviews

Interviews offer significant potential for ethical issues due to the researcher's control and personal contact.

• Researcher's Control: Personal contact, non-standardized questions, face-to-face observation, and incremental knowledge development.

• In Face-to-Face Interviews:

- Avoid overzealous questioning and pressing for responses.

- Clarify the right to decline responding to any question.

• Avoid demeaning questions.

• Consider the time and location of the interview carefully.

Ethical Issues in Observation

- Clarify Boundaries: Define what is permissible to observe and avoid observing private behavior (e.g., personal calls).

• Reactivity:

Participants may alter their behavior due to the researcher's presence.

- Covert Observation: Can avoid reactivity but raises ethical questions ("Do the ends justify the means?").

- Habituation: Participants may adapt to the observer's presence over time, reducing reactivity.

- Debriefing: Inform participants about the observation's purpose and what occurred afterward.

Researcher's Personal Safety

The researcher's safety is an important ethical consideration.

• Avoid revealing personal information (e.g., home address, phone number).

• Meet participants in safe spaces.

• Conduct data collection during daytime hours.

• Inform others about your arrangements, including your location.

Ethical Issues in Data Analysis and Reporting

Lack of objectivity at this stage can distort conclusions.

• Avoid Selectivity: Do not selectively report data.

• Accurate Representation: Do not misrepresent the statistical accuracy of data.

• Maintain Confidentiality and Anonymity:

- Ensure assurances given to participants are upheld.

- Consider if participating organizations can be identified by others piecing together characteristics.

• Allow organizations to review work to understand context if they might be named.

- Avoid reporting data clearly attributable to a specific individual.

- Use generalization (e.g., avoid specific ages, dates, locations, names of countries, real names, actual organizational names, or job positions).

- Impact of Findings: Consider how research findings will affect participants and try to construct research questions and objectives to avoid adverse effects.

Principles of Data Protection and Data Management

• Data Protection Legislation: Be familiar with relevant laws.

- Personal Data: Data relating to a living person that identifies them, possibly in combination with other information.

- Sensitive Personal Data: Includes information about racial or ethnic origin, political opinions, religious beliefs, trade union membership, physical or mental health, sexual life, or alleged criminal offenses.

- Data Security: Personal and confidential data must be properly labeled and securely kept. This includes original notes, recordings, drafts, transcriptions, re-recordings, backups, and anonymized versions.

- Anonymization Techniques: Use aggregating data, pseudonyms, and higher levels of generalization to remove personal identifiers.

- Separation of Data: Data containing personal identifiers should be held securely but separately from anonymized versions.

The Research Report

Introduction to the Research Report

A research report serves to clearly describe all stages of the research process. Its primary purpose is to offer a detailed account of what was done, from the initial problem statement and literature review to data collection, analysis, and interpretation of results.

Key Characteristics of a Well-Written Report

- Clarity: Information should be presented in an understandable manner.

• Conciseness: Avoid unnecessary jargon or overly lengthy explanations.

- oherence: Ideas should flow logically from one section to the next.

- sis: Important aspects of the research should be highlighted.

- ganization: Paragraphs should be well-structured, with smooth transitions between topics.

• Specificity: Use precise language and avoid ambiguity.

• Objectivity: Present facts and evidence, rather than personal opinions.

• Replicability: A colleague should be able to replicate the research after reading the report.

- Audience Appropriateness: Tailor the report's content, length, and level of detail to the intended audience.

- Clarity of Purpose: State the research aim or purpose early in the report.

Purpose of the Written Report

The purpose of a research report can vary:

• Descriptive: To provide detailed information on specific areas of interest.

- Problem-Solving with Alternatives: To offer several potential solutions or recommendations to a problem, along with their pros and cons.

- Comprehensive Problem Identification and Solution: To identify a problem, study it thoroughly, and offer a definitive solution.

• Scholarly Publication: To present the findings of basic research in academic journals.

The Audience for the Written Report

The audience significantly influences the report's organization, length, focus, and data presentation.

- Executives: Often benefit from an executive summary for a quick overview. They may prefer graphs and charts over tables.

• Technical/Statistical Audiences: May require more detailed data and statistical explanations.

- General Managers: Primarily interested in the problem, findings, conclusions, and recommendations.

Tact is important when presenting potentially unpalatable findings, ensuring they are presented objectively and non-judgmentally.

Structure of the Research Report

A standard research report typically includes the following sections:

Title Page

• Includes the title of the research, author's name, institution, supervisor(s), and date.

- The title should be descriptive and accurately reflect the content. A subtitle can be used for further clarification.

Executive Summary or Abstract

• A brief overview of the entire research study.

• Highlights the problem statement, methodology, key findings, conclusions, and recommendations.

• Typically one page or less.

• Crucial for busy readers to grasp the essentials.

Preface

• Contains background information not fitting into the main text.

• May include reasons for the study, difficulties encountered, and acknowledgments.

• Distinct from the introduction.

Letter of Authorization (Optional)

- A copy of the authorization letter from the sponsor, approving the study and detailing its scope.

Table of Contents

- Lists headings and subheadings with corresponding page numbers.

• Serves as a guide for the reader.

- May include separate lists for tables and figures.

List of Tables, Figures, and Other Materials

Body of the Report

This section typically comprises two main parts:

Theoretical Part (Literature Review)

• An in-depth exploration of relevant existing literature.

• Should be selective, goal-oriented, thorough, and critical, not just a summary.

• May conclude with a theoretical framework and hypotheses (for deductive research).

- The title of this chapter should reflect its specific content.

Empirical Part (Methodology and Findings)

• Methodology:

• Detailed and transparent description to enable replication.

• Setting: Research location and ethical conside

• Participants: Number, selection criteria, characteristics, and handling of refusals.

• Materials: Instruments used (tests, scales, questionnaires, etcetera), their development, and data analysis methods.

• Procedures: Training of interviewers/observers, context of data collection, instructions given to participants, duration, and timing of data collection.

• Findings (Results):

• Reporting of factual discoveries from the research.

- Can include tables, graphs, and verbatim quotes.

• Report all findings, including those that contradict hypotheses.

- Structure findings logically, either in the order of research objectives or thematically by importance.

• Avoid opinions or interpretations in this chapter.

Final Part of the Report (Discussion and Conclusions)

• Discussion:

- Interpretation of the findings presented in the previous chapter.

• Relate findings to research goals, questions, and hypotheses.

• Start compiling this section early in the writing process.

- Contain supplementary material that is "interesting to know" but not essential to the main text.

• May include organization charts, interview transcripts, questionnaires, detailed data, etcetera

• Appendices should be labeled sequentially (e.g., Appendix A, Appendix B).

Oral Presentation

While the written report provides comprehensive details, an oral presentation aims to communicate key aspects effectively and engagingly within a limited timeframe (e.g., 20 minutes).

Characteristics of a Good Oral Presentation

• Planning and Rehearsal: Crucial for timing, content, and delivery.

- Audience Focus: Emphasize aspects most relevant to the audience (e.g., problem, findings, recommendations for managers; data analysis for statisticians).

- Visual Aids: Use charts, graphs, images, and other visuals to enhance understanding and maintain interest.

• Clear and Auditory Delivery: Speak clearly, audibly, and at an appropriate pace.

• Engaging Presence: Maintain eye contact, use appropriate gestures, and modulate voice.
