Proportionate stratified sampling involves selecting a sample proportionally from each stratum based on the size of the stratum in the entire population. This ensures that each stratum is represented adequately in the sample, and provides more accurate estimates for the population as a whole. Systematic random sampling involves selecting every nth individual from a list or population, while stratified cluster sampling involves dividing the population into clusters and randomly selecting clusters to sample from. Disproportionate stratified sampling involves selecting different sample sizes from each stratum, which can lead to biased estimates if not properly accounted for.
