# Stratified Sampling

Students learn the difference between different types of sampling methods and how to calculate a stratified sample size using equal proportions.  As learning progresses students are challenged to work the problem in reverse by finding the population of each strata given the sampling size.
##### Differentiated Learning Objectives
• All students should be able to find out what proportion of the population is in each stratum.
• Most students should be able to calculate the number of people to be sampled in a stratum.
• Some students should be able to calculate the total stratified sample size given the number of people sampled in a stratum
