As the variances are always positive, the result will also always be positive. Hence, the F Test equation used to compare two variances is given as: F_value = v a r i a n c e 1 v a r i a n c e 2 i.e. F_value = σ 1 2 σ 2 2 WebDec 27, 2024 · From the output table we see that the F test statistic is 2.358 and the corresponding p-value is 0.11385. Since this p-value is not less than 0.05, we fail to reject the null hypothesis. This means we don’t have sufficient evidence to say that there is a statistically significant difference between the mean exam scores of the three groups. dnd beastman race
