AMOSTRAGEM ESTRATIFICADA PROPORCIONAL ✅ INTRODUÇÃO À ESTATÍSTICA #10

It consists of dividing the population into subgroups (strata) that denote a homogeneity greater than the homogeneity of the entire population, under 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 make a proportional stratified sample? If we talk about a proportional stratified sample, each Wh is equal to the proportion that this layer represents in the population. If we talk about the optimal stratified sample, each Wh is calculated based on the dispersion within each layer.
