WebThe P-value is determined by comparing F* to an F distribution with 1 numerator degree of freedom and n-2 denominator degrees of freedom. In reality, we are going to let Minitab calculate the F* statistic and the P-value for us. Let's try it out on a new example! WebANOVA is inherently a 2-sided test. Say you have two groups, A and B, and you want to run a 2-sample t-test on them, with the alternative hypothesis being: Ha: µ.a ≠ µ.b. You will get some test statistic, call it t, and some p-value, call it p1. If you then run an ANOVA on these two groups, you will get an test statistic, f, and a p-value p2.

P-value defines the probability of getting a result that is either the same or more extreme than the other actual observations. The P-value represents the probability of occurrence of the given event.

WebJun 2, 2012 · Suppose we compute the p-value for different F values. This is the upper tail of the F distribution, so we subtract the cdf from 1. We can do this okay for F=2, but we get zero for F=20 because the cdf is too close to 1 and the difference is less than eps: We can instead compute the p-value as the lower tail of 1/F and swapping the degrees of ...
