Question

Quizplus · Accepted Answer

A stratified sample is a probability sample that involves dividing the population into subgroups and then randomly selecting participants from each subgroup in proportion to their representation in the population. This ensures that every subgroup is represented in the sample, and the results can be generalized to the entire population. The other options (A) Convenience sample, (B) Quota sample, and (D) Judgment sample are all non-probability samples, which means that participants are selected based on some criteria other than random selection, making it difficult to generalize the results to the entire population.
