Purposive sampling is defined as selecting participants based on

• A. Specific topics or characteristics to gain in-depth data.
• B. Representativeness of the population at large.
• C. Random chance.
• D. Time constraints and accessibility.

Answer: (A)

Purposive sampling focuses on selecting participants who have specific topics or characteristics that will best illuminate the issue you’re studying. The goal is deep, information-rich data about a focused question, not to produce a sample that mirrors the broader population. This non-probability approach is common in qualitative research because it’s the most efficient way to access cases that can provide detailed understanding of particular experiences or phenomena. It’s different from aiming for representativeness, which is typical of probability sampling, and from choosing participants simply because they’re easy to recruit, which would be convenience sampling. In practice, you’d deliberately choose people who have the relevant experiences, knowledge, or conditions to shed light on the research question, allowing for a richer, more nuanced analysis.
