Variables

Variables are computable expressions that can be used to simplify validation and enabling conditions that use complex expressions. The content of a variable can be substituted into question text or static text to provide text that is more informative and dynamic. Also, calculated variables are included in the export data files.

Sections

Any questionnaire created with this designer tool consists of sections and must have at least one section. Every section can in turn contain one or more: Sub-sections, Question, Roster, Static Text, and Variables.
 
 

Sub-sections

Subsections can contain one or more static-texts, questions, other sub-sections and rosters. They are used to group a set of questions related to a specific topic. For instance in household surveys a subsection can be used to group the questions related to the household’s characteristics. The main difference between subsections and rosters is that the questions within a sub-section are only asked once in an interview.
