Webb7 feb. 2024 · Stratified sampling is one, in which the population is divided into homogeneous segments, and then the sample is randomly taken from the segments. Cluster sampling refers to a sampling method wherein …
The population within a cluster should ideally be as heterogeneous as possible, but there should be homogeneity between clusters. Each cluster should be a small-scale representation of the total population. The clusters should be mutually exclusive and collectively exhaustive. A random sampling technique is then used on any relevant clusters to choose which clusters to include in the study.
