WebThe ratio of between-groups and within-groups variability produces a F statistic. See the following formula: F = B e t w e e n − g r o u p s − v a r i a b i l i t y w i t h i n − g r o u p s − v a r i a b i l i t y. An F statistic will become larger if the between-groups variability rises and the within-groups variability stays the same.
