In this post, we will initial discuss why we have to have a default test and why a two-step procedure where researchers determine whether or not to use Welch’s t-test based on a verify of the assumption of normality and equal variances is undesirable. Then, we will go over whether or not the assumption of equal variances is plausible in psychology and point out study places where this assumption is implausible.
