Cluster Sample


A cluster sample is a probability sample distinguished by a two-step procedure in which

  1. the parent population is divided into mutually exclusive and exhaustive subsets, and
  2. a random sample of subsets is selected.

If the investigator then uses all of the population elements in the selected subsets for the sample, the procedure is one-stage cluster sampling.

If a sample of elements is selected probabilistically from the subsets, the procedure is two-stage cluster sampling.[1]
