Cluster sampling is a type of EPSEM sampling technique in which the population is divided into clusters or groups, usually based on geographic proximity, and a random sample of clusters is selected for study. This technique is commonly used in large-scale surveys where it is not practical to sample the entire population, and is often more cost-effective and efficient than other sampling methods. Simple random sampling involves selecting individuals at random from the population, while proportional sampling involves selecting individuals based on their proportion in the population. Non-scientific sampling refers to any sampling method that does not follow standard scientific protocols. Therefore, cluster sampling is the best choice when EPSEM sampling technique often uses geographical areas.
