The F value in the ANOVA test also determines the P value; The P value is the probability of getting a result at least as extreme as the one that was actually observed, given that the null hypothesis is true. The p-value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically в‰¤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis..
