Which sampling technique involves dividing the population into groups and randomly selecting entire groups?

Understand the Problem

The question is asking which specific sampling technique includes the process of dividing a population into groups and randomly selecting entire groups from those divisions. This is typically related to studies in statistics or research methodology.

More Information

Cluster sampling divides the population into groups, or clusters, and then randomly selects entire clusters for study, making it distinct from stratified sampling, which samples from within each group.

Tips

A common mistake is confusing cluster sampling with stratified sampling. Remember, in cluster sampling, whole groups are selected, whereas in stratified sampling, random samples are taken from each group.
