The mean square within treatments is the estimate of the variance within treatments, which is calculated by dividing the sum of squares within treatments by the degrees of freedom within treatments. The degrees of freedom within treatments is equal to the total sample size minus the number of populations, so the mean square within treatments is equal to SSE/(nT - K).
