I have a question, one of the assumptions of ANOVA is normality in the data or normality in the residuals?

[@puterizulaikha6528]

What if it has four variables, how the ANOVA ?

[@HealthGIS]

Sorry for the late response.
It doesn't matter. You can use ANOVA to compare the means of two or MORE groups.
