ANCOVA (Analysis of Covariance) is used to equalize initial differences between two groups before examining group differences. It does this by controlling for the effects of covariates (variables that could affect the outcome) that may be different between the two groups. ANOVA (Analysis of Variance) is a statistical test used to compare means between two or more groups, but it does not control for covariates. MANOVA (Multivariate Analysis of Variance) and repeated-measures ANOVA are also not focused on equalizing initial differences between two groups, but rather on analyzing differences in multiple outcomes or over multiple time points, respectively.
