Cluster Sampling - definition(s)

Cluster sampling - Sampling a population by taking samples from a smaller number of subgroups (such as geographic areas) of the population. The subsamples from each cluster are combined to make up the final sample. For example, in sampling sales data for a chain of stores, one may choose to take a subsample of a representative subset of stores (each a cluster) into a cluster sample rather than randomly select sales data from every store.
