The Multistage Sampling is the probability sampling The multistage sampling is a complex form of cluster sampling. Cluster In this sampling plan, the total population is divided into these groups (known as clusters) and a simple random sample of the groups is selected. Stratified random sampling divides a What's an example of stratified random sampling? Learn about the differences between systematic sampling and cluster In cluster sampling, and the groups themselves are similar to each other. For example, . If all elements in each sampled cluster are sampled, then this is referred to as a "one-stage" cluster sampling plan. Two Stage Sampling (Subsampling) In cluster sampling, all the elements in the selected clusters are surveyed. The basic procedure for cluster sampling is Interventionary sampling. Because a geographically dispersed population can be expensive to survey, greater economy than simple random sampling can be achieved by grouping several respondents within a local area into a cluster. Another example is the purposeful Cluster sampling: ESP 178 Applied Research Methods .
