Web3 de nov. de 2024 · This is a standard one-factor ANOVA with three levels of the factor. Because the sample means are quite different and the sample standard deviations are relatively small, it turns out that the F-statistic is very large, which makes the P-value essentially 0. (Computations from Minitab 17; format slightly edited for brevity.)

WebThe F ratios are not very informative by themselves, but are used to determine P values. P values.
