i have 3 group variables (faculty at the uni, workcategory and careertype). faculty has i think 5 undercategories, workcategory 8 and careertype has 9
and for my hypothesis testing i need 13 Variables (e.g. grade, fantasy, self-efficacy, ...)
do i need to test for normality each group variable on each level for each variable? or is it sufficient to just test each groupvariable for normality and then the distribution of each variable?
