Thank you for your videos, they are very helpful. I have a question though if Levene's test was significant (violated) what would you suggest to do? Let's say the sample size was 200, Thank you in advance

Dear Professor, how can we contrast among four groups in 2*2 factorial anova? I have to compare among four groups/treatments (A1B1, A1B2, A2B1, A2B2) to validate my hypotheses.
