WebIn general, we reject H 0 if F* is large — or equivalently if its associated P-value is small. The test applied to the simple linear regression model. For simple linear regression, it turns out that the general linear F-test is just the same ANOVA F-test that we learned before. As noted earlier for the simple linear regression case, the full ... WebDec 27, 2024 · To perform a one-way ANOVA on this data, we will use the Statology One-Way ANOVA Calculator with the following input: From the output table we see that the F test statistic is 2.358 and the corresponding p-value is 0.11385. Since this p-value is not less than 0.05, we fail to reject the null hypothesis.
