Hi, colisters:

I've just returned from a looong weekend. I hope than my particular 
solution to this problem is not too late.

Paul, run this code, and you will get the mean you want on the output 
window:

VARSTOCASES
 /MAKE score FROM score1 score2 score3 score4
 /INDEX = Index "Index"(4)
 /KEEP =
 /NULL = KEEP.

DESCRIPTIVES
  VARIABLES=score
  /STATISTICS=MEAN .



HTH


Frederic

[SPSSX-L] calculate mean of two separate variables






Hi all,

I guess this is an easy one...

In SPSS, how do I calculate a mean for the values of two (or more) 
separate variables?
After all, the (overall) mean of var X and var Y is NOT the mean of the 
mean of var Y and the mean of var Y!

Thanks in advance, any help will be appreciated!

Paul
