Subgroups might be based on company size, gender or occupation (to name but a few). Stratified sampling is often used where there is a great deal of variation within a population.

Comparison with stratified sampling: The systematic sample can also be viewed as if arising as a stratified sample. If the population of Nnk units is divided into n strata and suppose one unit is randomly drawn from each of the strata. Then we get a stratified sample of size n. In doing so, just consider each row of the following arrangement as a

regolith reveal that it is stratified with many buried soil horizons. The maturity of a regolith sample is the integrated exposure that it had to the micrometeorite and solar wind environment. Maturity is variously measured by the agglutinate content, grain size distribution, and/or the amount of implanted solar wind rare gases.
