The calculator will automatically find this value for you. This tells us that the cumulative probability is 0.78300. This is the area to the left of the F statistic in the F distribution. Typically we're interested in the area to the right of the F statistic, so in this case the p-value would be 1 - 0.78300 = 0.217.Using Statkey, generate a randomization distribution using at least 4000 samples.
