Hi, i have a following problem, concerning the building of means per Recall and ID ID Recall TotalScore 001 1 4 001 2 2 002 1 4 002 2 0.5 003 1 4 003 2 1 I want to create the means out of the TotalScore for the two Recalls, by every ID; so that it should be like ID TotalScore_mean 001 3 002 2.25 003 2.5 I thought about the proc means procedure and a class-statement for ID, but it is not working for me. I would be really happy if someone could help me. Best, Nina
