Hi. I have a question. Although I've already learned that homogeneity of variance is not an assumption of paired t-test, should I test for the homogeneity of the difference? If so, what test should I use? I am not yet that familiar with Pitman-Morgan Test. I'm thinking if I could use Levene's instead.
