Case studies involve an in-depth, detailed investigation of a single individual, group, or event. This method provides rich qualitative data that aims to explore complex issues not easily studied through other methods.

Core Definition

Depth and Scope

This method provides rich qualitative data that aims to explore complex issues not easily studied through other methods. The focus is on a single individual, group, or event, demanding an in-depth, detailed investigation.

Key Features

1

Depth over breadth

Focus on detail and complexity rather than large sample sizes.
2

Multiple data sources

May include interviews, observations, psychological tests, and archival records.
3

Flexibility

Can be exploratory, descriptive, or explanatory.

Types of Case Studies

📋

Descriptive

Provide a thorough description of phenomena or individual characteristics.
🧪

Explanatory

Test hypotheses or explain causal mechanisms.
🔍

Exploratory

Investigate phenomena to develop new theories or research questions.

Strengths vs. Limitations

✅
The Strengths (Advantages)
  • Provides detailed and holistic understanding of complex issues.
  • Can capture unique or rare phenomena that larger studies may miss.
  • Useful in developing hypotheses and theories.
  • Enables study of real-life contexts and long-term processes.
❌
The Limitations (Disadvantages)
  • Limited generalizability due to focus on one case or small samples.
  • Subjectivity and researcher bias can influence data collection and interpretation.
  • Difficult to replicate.
  • Time-consuming and resource-intensive.

Research Pro Tip

💡

Maximizing Utility: Case studies are most powerful when used to generate new theory or understand the mechanism of a specific outcome, rather than aiming for statistical generalization.
