The F statistic is calculated as the ratio of the mean square for treatment to the mean square for error. With three treatments and five measurements each, the degrees of freedom for treatment is 2 and for error is 12. Mean square for treatment is 17.0493/2 and mean square for error is 8.028/12. The F statistic is (17.0493/2) / (8.028/12) = 12.74.
