              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
