Test statistic calculated as:

$${\chi_F}^2 = \frac{SS_{Total}}{SS_{Error}} \sim \chi_{k-1}^2 \text{ for
large n ($>$15) and k ($>$5)}$$
large n ($>$15) and k ($>$4)}$$

For smaller n and k, the $\chi^2$ approximation is imprecise and a look up of $\chi_F^2$ values that were approximated specifically for the Friedman test is suggested.
