This involves dividing the population into subgroups (strata) that demonstrate greater homogeneity than the homogeneity of the entire population, based on the analysis of study variables. A proportional stratified sample ensures that each element of the population has the same probability of belonging to the sample. How to create a proportional stratified sample? In a proportional stratified sample, each Wh is equal to the proportion that this stratum represents in the population. In an optimal stratified sample, each Wh is calculated based on the dispersion within each stratum.
