## 12 Data transformations

The PSPP procedures examined in this chapter manipulate data and prepare the active dataset for later analyses. They do not produce output, as a rule.

• AGGREGATE |  | Summarize multiple cases into a single case.
• AUTORECODE |  | Automatic recoding of variables.
• COMPUTE |  | Assigning a variable a calculated value.
• COUNT |  | Counting variables with particular values.
• FLIP |  | Exchange variables with cases.
• IF |  | Conditionally assigning a calculated value.
• RECODE |  | Mapping values from one set to another.
• SORT CASES |  | Sort the active dataset.
