An independent measures design is a type of method used during a psychology experiment that involves two or more separate groups, each containing different individuals, where each participant only takes part in each condition once.

[edit] Advantages of independent measures design

The main advantages of using independent measures design in a psychology experiment is that there is no risk or order effects coming into play, which therefore increases the internal reliability of the experiment. Also as opposed to repeated measures, more participants are used which could therefore increase the external reliability of the experiment.

[edit] Disadvantages of independent measures design

One of the main disadvantages of using independent measures design is the potential for error resulting from individual differences of the participants of each separate group, which would affect the results and therefore the external reliability.
