Stratified Random Sample - GCSE Sociology Definition

A stratified random sample is a way of choosing a group of people to study, ensuring that all the different types or "strata" in a larger population are represented. Imagine a school with students from different year groups, and you want to study student opinions. To get a fair sample, you divide the students into year groups (the strata) and then randomly pick students from each group to create a sample. This helps make sure that your sample reflects the whole school, making your study more accurate and reliable. In GCSE Sociology, it's important because it helps researchers understand the views and behaviours of different segments within a population.
