I have exported data from a Qualtrics survey into SPSS. I have two groups, psychology, and law that are not in order in a mixed 2x2 Anova design. Both groups take three scales before and after watching a video. I need to create a variable called 'Group' and have my two student groups sorted into the two groups where psychology students are experiemental and law are the control. Then I need to create two more variables, one for pre test and post test where I will compute three scales. I need help with this please.
