Stratified Randomization
A sampling strategy where the population of interest is divided into representative "clusters" of individuals, among whom a random selection of subjects is drawn. Cluster sampling is often conducted when it is impossible or impractical to draw a simple random sample or stratified sample because the researcher cannot get a complete list of members of the population.
