In DataDynamic, there are different ways to create your own variables:
- Create a new base variable; this will add a new standard variable to the dataset using the specified data type. The default value for all respondents is set to MISSING.
- Create a new Calculated Variable; this will add a formula based variable to the dataset. Look here to find lots of information on calculated variables.
- Recode a variable; This will create one or more standard or calculated variable(s) based on existing ones. Look here to find lots of details on recoding variables.
- Create weight; DataDynamic allows you to create your own weight variables based on simple or RIM weighting. Please look here for more information on creating weight variables.
The new variables appear as public visible variables in the variable list.
