There are these issues that are bothering me about normality. As we know, means comparison of means require normailty.
Suppose if I am going to use an ANOVA testing, and my scale variable is not normal even after I do a LN or sqrt, what should I do?
It will be nice also if there is a way for me to know which normalisation method to use as in sqrt, LN, or something else based on some Statistics.
Thank you for any advice.
