Most of the examples presented here use the data file demo.sav. This data file is a ficticious survey of several thousand people, containing basic demographic and consumer information.

If you are using the Student version of SPSS, your version of the demo.sav is a representative sample of the original data file, reduced to meet the 1,500 case limit. Results that you obtain using that data file will differ from the results shown here.

All sample files used in these examples are located in the tutorial\sample files folder within the folder in which SPSS is installed.
