The overall steps to evaluate an ANOVA model are as follows: 1. Conduct an F test. a. If you do not reject H0 (the p-value is not small), then stop because there is no difference in means. b. If you do reject H0, then go to Step 2. 2. Consider unequal variances; look at the Levine test. a. If you reject H0, then go to Step 3 because the variances are unequal. b. If you do not reject H0, then go to Step 4. 3. Conduct Welch’s test, which tests differences in means, assuming unequal variances. a. If you reject H0, because the means are significantly different, then go to Step 4.
