Table for f test
WebYou will get some test statistic, call it t, and some p-value, call it p1. If you then run an ANOVA on these two groups, you will get an test statistic, f, and a p-value p2. If you look, then f = t² and p2 = p1. That is: the p-values are the exact same, and the test statistic for ANOVA is simply the square of the test statistic for the t-test. 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 i.e. F_value = σ 1 2 σ 2 2

WebIn probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W.
