WebMar 30, 2024 · To determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the significance level \alpha α. WebANOVA uses the F-test to determine whether the variability between group means is larger than the variability of the observations within the groups. If that ratio is sufficiently large, you can conclude that not all the means are equal. This brings us back to why we analyze variation to make judgments about means.
WebThe formal F -test for the slope parameter β 1 The null hypothesis is H 0: β 1 = 0. The alternative hypothesis is H A: β 1 ≠ 0. The test statistic is F ∗ = M S R M S E. As always, the P -value is obtained by answering the question: "What is the probability that we’d get an F* statistic as large as we did if the null hypothesis is true?"
