Cluster sampling is the method described in which the population is divided into subgroups or clusters, and then a sample is taken from each cluster. This method is useful when the population is diverse and geographically dispersed. It is efficient because it reduces the time and cost required to gather information about the population by grouping individuals into clusters.
