To binarize one or more variables, proceed as follows:
- Select single or multiple “Integer” or “Floating point” variables with the mouse.
- Click the Transform into binary variable
icon in the toolbar above the Variable List and confirm the query.
Therein the variable will be transformed into type “Boolean”, in which all values different from 0 are set to “false” – including the missing values or defined missing values.

The Transform into text variable icon allows you to transform all highlighted (non-text) variables into “Text” type variables.
