However, unlike SRS, the chance of each item being selected in an StRS does not need to equal the chance of any other item being selected. EXAMPLE: STRATIFIED RANDOM SAMPLE.

When using stratified random sampling to select 500 graduates by age group, the proportional formula is: (Sample Size ÷ Population Size) × Stratum Size. This ... In this article, we propose an exponential ratio type estimator for estimating the finite population mean in simple and stratified random sampling.
