A brief teaching note on the case study approach of Robert Yin as a research methodology

A brief teaching note on the case study approach of Robert Yin as a research methodology in social science (information from perplexity.ai)

My question: "Briefly highlight the main ideas of the case study approach (of Robert Yin) as a research methodology in social science with regard to the following topics: (1) favored research philosophy, (2) favored research approach(es) (both on (i) the research methods (i.e. quantitative, qualitative mixed methods) and (ii) the reasoning approaches (i.e. inductive, deductive and abductive reasoning).) (3) favored research method design techniques, (4) favored research method design quality criteria, (5) favored data analysis techniques, and (6) favored researcher's impression management approach in conducting the case study approach (of Robert Yin)."

The reply: "Here is a synthesis of the main ideas of Robert Yin's case study approach as a research methodology in social science, organized by the requested topics:

1. Favored research philosophy:
   Robert Yin's case study approach is largely aligned with a realist and positivist philosophy. He assumes a concrete reality independent of the researcher, which can be objectively studied through systematic methods. Yin sees case study research as oriented toward realism, emphasizing multiple variables and theoretical propositions for examining social phenomena.

2. Favored research approaches:

   • Research methods: Yin views case study research as a method that can incorporate qualitative, quantitative, or mixed methods data collection and analysis. He departs from the notion that case study is solely qualitative, encouraging a customized research procedure based on the case itself.

   • Reasoning approaches: Yin incorporates both deductive reasoning, especially through use of theoretical propositions guiding the case study, and also some inductive elements in analyzing empirical data. His design involves logical consistency primarily in deductive sense with the possibility of discarding rival explanations.

3. Research method design techniques:
   Yin emphasizes a structured research design, which is essentially a blueprint starting with research questions, identifying relevant data and sources, data collection procedures, and then data analysis. He supports both single and multiple case designs, as well as holistic or embedded cases. Yin advocates replication logic over sampling in multiple case studies. He also recommends development of a case study protocol and maintenance of a case study database for audit trail and reliability.

4. Research method design quality criteria:
   Yin outlines quality criteria including construct validity, internal validity, external validity, and reliability. He replaces statistical benchmarks with logic for eliminating rival explanations to strengthen findings. Multiple-case replications enhance external validity, and case study protocols enhance reliability.

5. Data analysis techniques:
   Data analysis in Yin’s approach involves pattern matching, explanation building, time-series analysis, and using theoretical propositions as analytic frameworks. Triangulation of multiple sources of evidence is critical. The aim is to produce logical and theoretically grounded interpretations rather than statistical generalizations.

6. Researcher's impression management:
   Yin stresses importance of rigor and transparency to avoid biases and researcher subjectivity. This includes careful documentation of procedures, an audit trail linking data to conclusions, protocol adherence, and proactive addressing of rival explanations. Researchers are encouraged to maintain an organized database of case materials and to be transparent about research limitations.

In sum, Yin advocates a rigorous, realist, and systematic case study approach with flexible but methodically sound designs, emphasizing theoretical grounding and quality criteria analogous to traditional research methods but tailored to the case study’s particularities."
