Compare and contrast simple random,systematic,stratified,and cluster sampling.
On Jul 01, 2024
Simple random sampling involves selecting items from the population in such a manner that each item has an equal chance of being selected.The other three methods have simple random sampling at their core but the population is subdivided into subgroups,based on some naturally occurring property or by other means.Systematic sampling calls for every nth item to be selected after a random first selection.Stratified sampling allocates a proportionate sampling from each natural subgroup.While cluster sampling follows the same random sampling within non-natural subgroups,each element in a randomly selected cluster is used in the sample.
