WebThe calculated F-statistic for a known source of variation is found by dividing the mean square of the known source of variation by the mean square of the unknown source of variation. ... p-value. From the F table, we can find F critical values that give us a certain area to the right. From the above table, the area to the right of 4.88 is 0.05 ... WebThe shaded area represents the probability of observing an F-value that is at least as large as the F-value our study obtained. F-values fall within this shaded region about 3.1% of the time when the null hypothesis is true. This probability is low enough to reject the null hypothesis using the common significance level of 0.05. We can conclude ...
