WebIf we’re hoping to show that the means are different, it's good when the within-group variance is low. You can think of the within-group variance as the background noise that can obscure a difference between means. For this one-way ANOVA example, the value that we’ll use for the variance within samples is the Adj MS for Error, which is 4.402.
