Quizplus · Accepted Answer

Both stratified and cluster sampling involve dividing the population into subpopulations or clusters as a component of the selection criteria. In stratified sampling, the subpopulations are chosen based on relevant characteristics such as gender, age, or socioeconomic status, and a sample is then randomly selected from each subpopulation. In cluster sampling, the population is divided into clusters, which may be geographic or organizational, and a random sample of clusters is chosen. The data are then collected from all units within the selected clusters.
