SPSS Defining Variables with 17 Different Examples
Defining a variable includes giving it a name, specifying its type, the values the variable can take (e.g., 1, 2, 3), etc. Without this information, your data will be much harder to understand and use. Whenever you are working with data, it is important to make sure the variables in the data are defined so that you (and anyone else who works with the data) can tell exactly what was measured, and how.
