When you have a list of all the students the fit into your population of interest and randomly select 100 students to be apart of your study, the type of sampling that you doing is stratified sampling.
A method of sampling from a population that can be divided into subpopulations is known as stratified sampling in statistics. When subpopulations within a larger population differ in statistical surveys, it may be advantageous to sample each subpopulation separately.
For example, if one is interested in differences between groups based on race, gender, or education, stratified random sampling is frequently used by researchers to learn about different subgroups or strata based on the entire population being studied. In this case, the subpopulation from the initial population is chosen.
