How to create a synchronous filter
Research Studio has a special feature: “Synchronous”-filter. This means that each row in a grid question will be asked only if the respondent has answered the corresponding category in a previous multiple question.
Sub-Question 1: Countries visited
Sub-Question 2: Evaluation of countries visited
- Select Sub-question 2 from the filter drop down menu. The filter builder opens
- Then specify “Synchronous filter” from the advanced options
- The created filter will now work as follows:
Only valid lines will show.
Note that the categories must be synchronous between the two questions and the number of categories in “Sub-Question 1” must at least be as many as in “Sub-question 2".
The synchronous filter may also be used between ordinary questions, i.e. they need not be sub-questions in the same question. Note that if this is the case, the written text in the "other" open text field will NOT be carried through.
