A covariate is used to adjust post-test scores. For example, when completing an experiment, the treatment group may have higher pretest scores than the control group. A covariate would then be used to adjust the post-test scores due to differences in pretest scores. A covariate is one way to control for extraneous variables (Delcourt, 2013).
