Stratified sampling involves dividing the population into subgroups or strata based on certain characteristics, then selecting a sample from each stratum. This method ensures that the sample is representative of the population and is often more efficient than other sampling methods. Area sampling involves dividing the population into geographic areas and then selecting samples from each area. Cluster sampling involves randomly selecting groups or clusters from the population and then sampling individuals within each cluster. Simple sampling involves randomly selecting individuals from the population, while comprehensive sampling involves sampling the entire population.
