This distribution is a continuous probability distribution and is used within the analysis of variance (ANOVA) that uses the F-test in which the actual calculated value is compared to the F-test statistic for hypothesis testing.

Rarely is the probability density function calculated mathematically. Thankfully that work has been done and F-tables with the most common levels of significance and degrees of freedom exist for reference.

**BE CAREFUL** when using tables. Some tables are for one-tailed test and others cover two-tailed test.

For a one-tailed test, the null hypothesis is rejected when the test statistic is greater than the value given in the F-table value.
