WebAn F-test is any statistical test in which the test statistic has an F -distribution under the null hypothesis. It is most often used when comparing statistical models that have been fitted … WebTo create an F-test we will use these same variances, the variance explained (SSR), the variance unexplained, and the sum of squares total (SST). We first need to obtain the mean square before the F. To do that, we just need to know what the d.f. will be for dividing the Sum of Squares values (and our instructor always gives us that).
