The steps to the calculation of the p Value are as follows:

Calculate SSBetween_Groups and SSWithin_Groups from the original data set.

Calculate MSBetween_Groups and MSWithin_Groups by MS = SS/df

Calculate the F Statistic by F = MSBetween_Groups / MSWithin_Groups

Calculate the p value by p Value = F.DIST.RT(F, dfBetween, dfWithin)
