Stratified probability sampling involves dividing the population into subgroups (or strata) based on certain characteristics and then selecting a random sample from each subgroup. This technique ensures that each subgroup is represented in the sample and is therefore considered to be more representative of the population as a whole than other sampling techniques. Cluster sampling involves randomly selecting entire groups or clusters from a population and sampling within those clusters, whereas simple random sampling involves randomly selecting individual members from the population. Systematic sampling involves selecting every nth member from a population.
