The distribution of all possible values of the f statistic is called an F distribution, with v 1 = n 1 - 1 and v 2 = n 2 - 1 degrees of freedom.

The F distribution is derived from the Student's t-distribution. The values of the F distribution are squares of the corresponding values of the t-distribution.
