Example Answer for Question 16 Paper 2: AS Psychology, June 2017 (AQA)

Section C - Research Methods

Question 16: Explain [2 Marks] - Stratified Sampling

Suggested Answer: A stratified sample might improve this study by making the sample more representative of the students in the sixth form centre. With stratified sampling, there will be a proportional representation of the subgroups within the sixth form centre, as determined by the researcher (e.g. a proportional representation of males/females or different subjects studied, etc.) This might improve the generalisability of the findings to the target population (students within a sixth form centre).
