Analysis of covariance (ANCOVA) allows you to control for or equalize initial differences between groups by using a covariate, which is a variable that is related to the outcome variable but not to the grouping variable. ANCOVA adjusts for the effects of the covariate, making the groups more comparable and providing a more accurate estimate of the treatment effect.
