WebFeb 11, 2024 · The F-test is usually used to compare the two standard deviations of two samples and check the variability. F-test is always carried out as a single-sided test as variance cannot be negative. Under the null hypothesis, the F-statistic follows the Snedecor’s F-distribution. The F-test can be applied on the large sampled population. WebF-statistics are the ratio of two variances that are approximately the same value when the null hypothesis is true, which yields F-statistics near 1. We looked at the two different variances used in a one-way ANOVA F-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.
