Question

in a study, the sample is chosen by asking our 40 closest friends
what is the sampling method?
○ simple random
○ stratified
○ convenience
○ none of these

Explanation:

Convenience sampling involves selecting individuals who are easily accessible or convenient to sample. In this case, choosing the 40 closest friends is a form of convenience sampling as it is based on ease of access (they are the researcher's close friends) rather than random selection (as in simple random sampling where every member of the population has an equal chance of being selected) or dividing the population into strata (as in stratified sampling). So the sampling method is convenience sampling.

Answer:

C. Convenience
