Matched Group Design Definition | Psychology Glossary

A matched group design, or matched subjects design, is when an experiment is designed to control for individual differences by matching similar subjects with each other.

For example, if researchers needed two groups to compare how different animals reacted to the flavor of the new Taco Pumpkin Spice Supreme Burrito, they’d likely make each group consist of the same number of cats, dogs, rats, cockroaches, and any other animal that would dare eat such a monstrosity. In this way, they could more accurately compare like-for-like and be more confident in their study’s results.
