I divided my dataset in 10 groups (because I have 10 different industries). Now, in SPSS one can use "select cases" to get rid of outliers.This is fine. However, I want to apply a different "select cases" rule for each of the 10 groups because it would be wrong to just set the same threshold value for each industry. Does anybody know how to do it?
Many thanks for your help guys!
