Sampling is crucial in psychology but can be difficult to understand.

This film offers a helping hand with a series of visual images that take students through conceopts like:

  • target population,
  • types of samples,
  • representativeness and
  • generalisability. 

 

It then looks at how sampling is actually carried-out, illustrating differences between probability and non-probability sampling, why different techniques are used and their strengths and limitations. 

The final part looks at how this knowledge can be used to help students evaluate any study based on sampling.
