Quizplus · Accepted Answer

Stratified sampling involves dividing the population into mutually exclusive and exhaustive subsets (called strata), and then selecting a simple random sample from each strata. This ensures that the sample is representative of the population across all the strata. Option A describes the process of stratification, but does not distinguish it from other forms of probability sampling. Option B describes the property of all probability sampling methods. Option C describes the property of systematic sampling. Option D is the correct answer as it describes the unique process of stratified sampling, while Option E is not correct as Option D is the correct answer.
