Interpreting f statistic
WebIt is called the F distribution, named after Sir Ronald Fisher, an English statistician. The F statistic is a ratio (a fraction). There are two sets of degrees of freedom; one for the numerator and one for the denominator. For example, if F follows an F distribution and the number of degrees of freedom for the numerator is four, and the number ... WebOct 6, 2016 · 1 Answer. Sorted by: 3. You don't usually "use" the degrees of freedom for anything. It's needed to work out the p value of the F statistic, since every F distribution (each identified by its two degrees-of-freedom parameters) is different. Since R - like most other statistical software - calculates that p-value for you, you don't necessarily ...
