Goal and preparation
This guide shows how to:
- build an Array question with custom answer options;
- apply clean randomization across experimental conditions;
- avoid common syntax and display errors.
Example used: 4 sub-questions and a 6-point response scale (from “6 - I like it very much” to “1 - I do not like it at all”).
