Question

Which of the following method relies least on representative sampling?

• A. Experiment
• B. Survey
• C. Case Study
• D. Longitudinal Study

Hint:

Case studies involve analysis of a single subject.

Answer 1

The Correct Option is C

Case studies involve intensive analysis of a single subject or a very small group and do not rely on representative sampling.

• Characteristics: Focused, in-depth exploration of unique cases.
• Limitations: Findings are not easily generalizable to a larger population.

In contrast:

• Surveys: Require broader, representative samples to generalize findings.
• Experiments: Often use representative sampling to ensure valid conclusions.
• Longitudinal studies: Involve repeated observations over time with a larger, representative sample.
