Summary of “9th February Research Methodology By Prof Ravindran”
Main Ideas and Concepts
1. Philosophical Foundations of Research Methodologies
- Quantitative Research is grounded in realism and positivism, assuming an objective reality independent of the mind, studied using natural science methods.
- Qualitative Research is based on constructivism, emphasizing that social reality is a mental construct, subjective and interpreted through human experiences.
- Two opposing ontologies:
- Realism: The world exists independently of human perception.
- Constructivism: Social reality is constructed by human minds, beliefs, values, and meanings.
2. Naturalism vs. Anti-Naturalism
- Naturalism: Humans are part of nature, and social sciences should use natural science methods (methodological naturalism).
- Anti-naturalism: Humans are fundamentally different because they possess a mind with qualities not found in the natural world, requiring different methodologies (interpretivism).
3. Qualities Unique to the Mind (Relevant to Social Sciences)
- Qualia: Subjective experiences (e.g., pain) that cannot be empirically observed.
- Intentionality: Actions are driven by beliefs and desires.
- Rationality: Humans attribute reasons to their actions, unlike mechanical natural phenomena.
4. Interpretivism and Thick Description
- Social phenomena must be understood by interpreting meanings, beliefs, values, and intentions behind actions.
- Thick Description: An anthropological concept describing not just observable behavior (thin description) but also the intentions and meanings behind it.
- Verstehen (Interpretative Understanding): Empathetic understanding of social actions, contrasting with law-governed natural science explanations.
5. Example of Interpretivism: Wink vs. Social Meaning
- A natural science explanation (muscle movement) is insufficient to explain social reactions (e.g., a wink being offensive).
- Social actions require understanding intentions and meanings.
6. Max Weber’s Interpretative Sociology and Instrumental Rationality
- Social actions are explained by beliefs and desires (intentionality).
- Example: Weber’s study of Protestant ethics and capitalism emergence explained by Calvinists’ beliefs about salvation and wealth accumulation.
- Distinction between explanation (outsider’s view) and understanding (insider’s view).
7. Quantitative Research Methodology
- Focuses on explanation through hypothesis testing.
- Steps:
- Formulate a problem or research question.
- Develop a hypothesis (tentative, falsifiable statement about cause-effect relationships).
- Identify and operationally define variables (make concepts measurable).
- Collect data to test the hypothesis.
- Hypothesis must be empirically testable.
- Hypotheses generally derive from existing theories or prior knowledge, not directly from data.
- Example used: A boy diagnosing a princess’s anorexia nervosa by hypothesizing it is caused by love, operationalizing love as increased pulse rate when recalling the loved one.
8. Qualitative Research Methodology
- Focuses on understanding through concept maps (insider’s view).
- No preconceived hypothesis; data collection is direct and naturalistic (e.g., interviews, narratives).
- Data are verbal or pictorial, analyzed by:
- Documentation (transcribing narratives),
- Coding (extracting themes/concepts),
- Concept map construction (linking concepts into a holistic understanding).
- Sampling is non-probability based (purposive, snowball, theoretical).
- Example: The princess narrates her feelings of love; the boy codes and creates a concept map of the experience of being in love.
9. Triangulation in Qualitative Research
- Since qualitative research is subjective, triangulation ensures validity by:
- Member checking: Sharing findings with participants for confirmation.
- Expert triangulation: Consulting other experts.
- Methodological triangulation: Using multiple methods to confirm findings.
10. Mixed Methods and Choice of Approach
- Choice depends on the nature of the research object:
- Real, objective phenomena → Quantitative.
- Constructed, subjective phenomena → Qualitative.
- Mixed methods combine both but investigate different aspects.
Methodologies and Instructions
Quantitative Research Steps
- Problem Formulation: Identify a clear research problem/question.
- Hypothesis Development: Create a falsifiable, empirical hypothesis.
- Variable Identification: Determine independent and dependent variables.
- Operational Definition: Define variables in measurable terms.
- Data Collection: Gather data specifically to test the hypothesis.
- Hypothesis Testing: Analyze data to accept or reject the hypothesis.
Qualitative Research Steps
- No Preconceived Hypothesis: Avoid imposing outsider assumptions.
- Direct Data Collection: Use naturalistic methods (interviews, conversations).
- Documentation: Transcribe verbal data.
- Coding: Extract meaningful codes/themes from data.
- Concept Map Construction: Build a conceptual framework representing insider understanding.
- Triangulation: Validate findings through member checking, expert review, and multiple methods.
Examples and Illustrations
- Wink Example: Demonstrates difference between natural science explanation and social meaning interpretation.
- Calvinist Capitalism: Illustrates how beliefs and desires explain social phenomena.
- Princess Story: Contrasts quantitative (hypothesis testing about love causing anorexia) and qualitative (narrative and coding of feelings) research methods.
- Stages of Love: Concept map showing emotional stages in fulfilled and frustrated love.
