In the example above, the first line after the AGGREGATE command requests that the aggregated data be saved in file "meaninc.sav" in subdirectory "subdir". The deviation of the individual incomes from the mean income then may easily be computed. You may request SPSS to compute these mean incomes by aggregating all cases in each group, save these incomes to a new data set and then match these mean incomes to your original data. For instance, you may wish to have in your data, for each case, a variable measuring how much this person's income differs from the mean income of all persons in the same occupational group. It means that new data are computed from an existing data set, and cases in the new data set refer to a group of cases. Aggregating your data can be a powerful tool.
