Web analysis of covariance (ancova) assesses group differences on a dependent variable (dv) after the effects of one or more covariates are statistically removed. The quantity cov[x, y] = e[(x − μx)(y − μy)] is called the covariance of x and y. It is commonly used to. Web adding a covariate into anova also reduces the degrees of freedom.
