Variables are key part of any dataset. They signify how your research is conducted and what types of analysis methods can be used. When using SPSS, it is important to know how to define and compute variables for your analysis.
QuestionPro auto-generates variable names by default and you generally don't need to change these. However, if you have customized question codes which you want to use in SPSS variable names, for better readability, you can select the option to use question codes in variable name when exporting a SPSS file for your survey data.
To download a SPSS file of your data, go to: My Surveys (Select Survey) » Analytics
Under Manage Data click on the Export option. Scroll down to the Statistical Package Export (SPSS) section. Select the toggle (switch) for display question code in variable name and click on download. On the popup, you can fix errors if any and click on export.
