The F-Distribution

What is the F-distribution?

The F-test uses the F-distribution to determine the probability of obtaining a test statistic as extreme or more extreme than the one observed, assuming that the null hypothesis is true (i.e., assuming that the means of the groups are equal). The F-distribution is a continuous probability distribution that has two parameters, the degrees of freedom for the numerator (df_between) and the degrees of freedom for the denominator (df_within).
