Stratified Sampling A Step By Step Guide With Examples вђ Otosection The document provides a step by step guide to stratified sampling. it begins by explaining when to use stratified sampling, such as when a population is diverse and you want to ensure proper representation of all characteristics. it then outlines the four main steps: 1) define the population and subgroups, 2) separate the population into mutually exclusive strata, 3) decide on the sample size. 160. 10. 170. we can calculate the sample of each grade using the stratified random sampling formula: sample for each grade = sample size population size*population of each grade. sample for grade 6 = 100 1000 * 180 = 18. sample for grade 7 = 100 1000 * 210 = 21. sample for grade 8 = 100 1000 * 280 = 28. Stratified sampling is a method of obtaining a representative sample from a population that researchers have divided into relatively similar subpopulations (strata). researchers use stratified sampling to ensure specific subgroups are present in their sample. it also helps them obtain precise estimates of each group’s characteristics. Step by step guide to stratified sampling. stratified sampling consists of four steps: define the population and subgroups; divide the population into strata; determine the sample size for each stratum; draw a random sample from each stratum; step 1: define the population and subgroups.
