The settings of Variable Numeric Set question type is very similar to the 'Variable Numeric' question type.  The only difference is the definition of variables (Step 8 of Guide of 'Variable Numeric' question type). Please  refer to the guide for general settings:  Guide of Variable Numeric Set question type   .

 

Step 8:  Set up variables

There are still two types of variables in variables:
