Categories and Dynamic Panels

Categories and Dynamic Panels

Categories can be used to store the characteristics of your panellists. It can contain information about for example allergies, shopping behaviour and food consumption behaviour. 
Using categories, and other information available in the panelist profile, the panel manager can create dynamic panels. A dynamic panel constantly checks and updates which panellists are eligible for the panel. This in contrary to a static panel, which is a fixed panel and does not change unless the panel manager manually adds or removes panellists.
In order to create a dynamic panel that includes a filter on category data, you first need to create the category.

For instance: to create a panel that is not allergic to lactose, the user first needs to create a category in EyeQuestion.

  4. Instruction Text: specify the question text that the panellist will see when adding a category into a questionnaire.
  5. Status: the current status of the category. When the category is in draft status, you can still make changes to the category. Once the status is changed to active you are not allowed to remove any existing category items. It is possible to still edit category information and items.
