In stratified sampling, the population is divided into strata or subgroups based on some characteristics. A subsample is then drawn from each stratum using simple random sampling technique. This ensures that each stratum is represented in the sample, which can improve the precision and accuracy of the estimates. Cluster sampling involves dividing the population into clusters and randomly selecting some clusters for the sample. Systematic sampling involves selecting every kth element from a list of the population. Convenience sampling involves selecting individuals who are easy to reach or available at the time of the study, which can lead to biased estimates.
