Question

Quizplus · Accepted Answer

Cluster random sampling involves selecting groups (or clusters) for the sample, not individuals. However, the disadvantage mentioned in D is not accurate. In cluster sampling, the entire cluster is typically surveyed, which means the sample size can actually be quite large depending on the number of individuals within each cluster. The statement in D seems to confuse cluster sampling with another method, such as stratified sampling, where the focus is on reducing the sample size by selecting specific strata.
