WebNov 3, 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.) WebFor a significance level of 0.05: If the p-value associated with the F-statistic is ≥ 0.05: Then there is no relationship between ANY of the independent variables and Y. If the p-value …
