Sampling of participants

Sampling of participants.

• Candidates should be able to:.
• describe what is meant by the sample and population, and the sampling techniques of opportunity sampling, random sampling and volunteer (self-selecting) sampling.
• evaluate different sampling techniques as used in psychological research, including generalisations.
• apply knowledge of sampling techniques to a novel research situation.

This matters because sampling of participants determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply sampling of participants to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Sampling of participants is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
