Analysis of covariance (ANCOVA) is a general linear model which blends ANOVA and regression. ANCOVA evaluates whether the means of a dependent variable (DV) are equal across levels of a categorical independent variable (IV) often called a treatment, while statistically controlling for the effects of other continuous variables that are not of primary interest, known as covariates (CV) or nuisance variables. Mathematically, ANCOVA decomposes the variance in the DV into varianc… WebReporting ANCOVA: What to report: Size of the F-statistics- online calculator- we want our score to be high (a value you get when you run an ANOVA test or a regression analysis to find out if the means between two populations are significantly different.
