How are average values calculated when there are hidden items?
When certain items are not shown to respondents due to display logic, the calculation of the average value for that question depends on the question type.
For constant sum, slider, star rating grid, and swipe cards questions, the average values are calculated with the formula:
value of shown items / number of participants who saw these items
For multiple choice and dropdown menu questions, the average values are calculated by:
value of all items (including hidden items) / number of participants who saw the question
