WebApr 9, 2024 · In Statistics, the F-test Formula is used to compare two variances, say σ1 and σ2, by dividing them. 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. Web$\begingroup$ In all parametric statistics there is a direct functional link between the test statistic (F in this case) and the p-value.
