问题
I have looked at the aggregate data questions on this forum and elsewhere - but I don't quite see an answer that helps me but that may be non-understanding on my behalf.I apologize. I have a huge amount of raw data test findings and I want to aggregate certain scores into one mean score. I can do this by creating a new variable in compute > transform but I cannot do this for 330+ by adding it 1 + 2 + 3 all by hand. My question is: How can I aggregate hundreds of scores and calculate a new mean score as a new variable in a quick and intelligent fashion that so far eludes me? For example, I have 339 latency measures for 50 participants. I want to calculate ONE overall latency score as a new variable. Thanks! I am desperate for direction.

If your variables are contiguous in the file you can use the SUM command using TO to specify the variables in simple syntax.
COMPUTE SumX = SUM(X1 to X330).
