Research Sampling

A representative research sample allows you to generalise your results and conclusions to the whole population of interest. However, if the sampling process is not carefully considered when designing the research project, you run the risk of having an ungeneralisable sample, from which you are unable to draw accurate inferences. It is therefore very important to have a good understanding of research sampling and the common errors to look out for. 

This guide provides information on research sampling best practices, how to ensure your sample is representative, and the various sampling techniques commonly used in qualitative and quantitative research methods.
