Perhaps the most common scenario for computing difference scores is where youve got a pre-test/post-test scenario, and you want to see how the dependent variable has changed between the two conditions (difference scores are sometimes termed change scores). We also need to name a new variable within which well store our new difference scores. Now you just need to type the name of the variable thatll contain the difference scores in the Target Variable box. WebFirst create or open a data file in SPSS. Verify this selection
