Students learn how to work out a stratified sample.
As learning progresses, students consider how to randomise samples.
Differentiated Learning Objectives
- All students should be able to determine the population proportion 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.
