Sampling Methods - GCSE Psychology Definition

What are Sampling Methods?

A researcher uses a specific sampling method in order to obtain participants that will take part in research (such as a lab experiment, a questionnaire, or an observation). The researcher must identify the target population and draw a sample of participants from it who will be asked to participate in the study. Once they have analysed the results, the researcher then generalises the findings across the target population

The type of sampling method used determines whether the results can be generalised to the target population, as some methods result in a more representative sample than others. Stratified sampling tends to produce the most representative sample, whereas opportunity sampling tends to result in the least representative and most biased sample.
