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). The Split File windowwill appear. Before calculating the statistical significance you will check certain assumptions. WebFirst create or open a data file in SPSS. From the SPSS output, find the r value (ignore any negative sign out the front) and N for Group 1 (males) and Group 2 (females). In order to split the file, SPSS requires that the data be sorted with respect to the splitting variable. Thats all there is to it. Select the option Organize output by groups. Repeat descriptive statistics on this data. Next, perform descriptive statistics on the selected data from the dependent variable.

The reason for this is the number of cases in each group. For example, suppose you have given your experimental subjects five different tests to complete, and you want to sum the scores of these tests for each subject, and fill a new variable with the totals.
