Two tailed f test in excel

WebThe F.TEST Function is used to calculate F statistic of two samples in excel internally and returns the two tailed probability of the F statistic under Null Hypothesis (H0). Note that the F.TEST function does not return the F test value, instead it returns it’s probability. If F.TEST returns value less than 0.05, we reject the null hypothesis. WebDec 28, 2024 · A Statistical F Test uses an F Statistic to match two variances, s1 and s2, by dividing them. The result’s always a positive number (because variances are always positive). The equation for comparing two variances with the f-test is: F = s21 / s22. If the variances are equal, the ratio of the variances will equal 1.
