When Obtaining A Stratified Sample The Number Of Individuals
When Obtaining A Stratified Sample The Number Of Individuals - Web when obtaining a stratified sample, the number of individuals included within each stratum must be equal. Define your population and subgroups. Statistics informed decisions using data. A stratified sample is one that ensures that subgroups (strata) of a given population are each adequately represented within the whole sample population of a research study. Within stratified samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population. Web this is found by dividing the number of people in the sample by the number of people in the population.
