Question

Quizplus · Accepted Answer

The F distribution is commonly used in testing hypotheses about variances. It compares the variances of two populations by calculating the ratio of their sample variances. In particular, it is used in the analysis of variance (ANOVA) test, which tests whether the means of three or more populations are equal. The other distributions listed are not typically used for testing hypotheses about variances.
