Which sampling method purposely draws from a part of the population assumed to have particular knowledge of what is being studied?

• A. Purposive Sample
• B. Accidental Sampling
• C. Probability Sample
• D. Simple Random Sample

Answer: (A)

Purposive sampling is used when you want to learn from people who have specific knowledge or experience related to the topic. By deliberately selecting individuals who are most likely to provide rich, relevant information, you can gain deeper insights into the phenomenon being studied. This approach is common in qualitative work where depth and expertise matter more than broad representativeness. This method fits the scenario because the goal is to draw from a part of the population assumed to hold particular knowledge about what is being studied. By focusing on those with the relevant expertise or experience, the data collected are more informative for understanding the research question. Accidental sampling relies on whoever is available by chance, which may not include the knowledgeable participants needed. Probability sampling and simple random sampling involve random selection to achieve generalizability, not targeted expertise, so they don’t align with the aim of gathering informed perspectives from a specific knowledgeable subgroup.
