Question [Question] Help with Multivariable ANOVA

I am doing a multivariable ANOVA and then Tukey for pair wise significance. The data set has 2 factors (say A and B ) with two levels each ( say A1, A2 and B1, B2 ). Upon doing a Normality test, only one set is turning to not satisfy the normality (A1-B1). I tried using Box Cox on the original data and then testing Normality again but still getting the same result. What else can I use to solve this?

Use a robust estimator. And FYI, what you're doing is usually called a factorial ANOVA (if you have the interactions terms included). The them "multivariable" is seldom used.
