Multi-stage sampling (also known as multi-stage cluster sampling) is a more complex form of cluster sampling which contains two or more stages in sample selection. In simple terms, in multi-stage sampling large clusters of population are divided into smaller clusters in several stages in order to make primary data collection more manageable.

Simple Random Sampling placed back in the population for re-sampling. An example of these procedures is shown in Figure 3-4 for the selection of three addicts from a populati on of nine. Since there are three persons in the sample, the selection procedure has three steps. Step one is the selection of the first sampled subject, 3-4 Sampling Procedure - an overview | ScienceDirect Topics Cluster Sampling. A compromise with sampling costs, sometimes useful in epidemiology, is cluster sampling. In this case, larger components of the population are chosen equilikely (e.g., a family, a hospital ward) and then every member of each component is sampled. A larger sample to offset the reduced accuracy usually is required. Sampling Methods | Types and Techniques Explained Sep 19, 2019 · Non-probability sampling methods In a non-probability sample, individuals are selected based on non-random criteria, and not every individual has a chance of being included. This type of sample is easier and cheaper to access, but you can’t use it to make valid statistical inferences about the whole population.
