Really simple question I can't figure out. I'm trying to run descriptives (Means/frequencies) on my data that are in long format/repeated measures. So for example, for 1 participant I have:
Participant Age ID 1 25 ID 1 25 ID 1 25 ID 1 25 ID 2 (Second participant .. etc) 30
So SPSS reads that as an N of 5 and uses that to compute the mean. I want SPSS to ignore repeated cases (Only read ID 1 data as one person, ignore the other 3). How do I do this?
Thanks in advanced.
