What is the decision rule in ANOVA always phrased in terms of Fobt being greater than Fcrit for the null to be rejected? That is, why is the ANOVA decision rule different from the t test decision rule in that the null is never rejected if Fobt is less than Fcrit?

What will be an ideal response?


The decision rule in an ANOVA is always phrased in “greater than” terms because the F distribution contains only positive values. Therefore, the critical region is always in the right-hand tail of the distribution.
