The use of this **Definition**: Multistage sampling is a complex form of cluster sampling where the population is divided into multiple stages, such as clusters, sub-clusters, and so on. Here we have several stages for the sample selection. Multistage sampling divides large populations into stages to make the sampling process more practical. In fact it is an extension of the concept of cluster sampling. What are the pros and cons of multistage sampling? Multistage sampling can simplify data collection when you have large, geographically spread samples, and you can obtain a probability sample Multi-stage sampling represents a more complicated form of cluster sampling in which larger clusters are further subdivided into smaller, more targeted groupings for the purposes of surveying. 0 INTROD.
