How to randomly assign a set of questions to different participants?
I have a project survey in which I need to ask participants to pairwise compare different elements.
I have 2 sets of questions which I would like to randomly assign to incoming participants: half of the participants should get a set of questions and the second half the other set. Both sets of questions find themselves in the middle of the questionnaire, meaning after participants go through one set or another, there are some questions which all participants shall answer.
As I am new to Questback Unipark tool, I would like to kindly ask you to help me. I know it is a matter of filtering and triggering, but what would the coding be in this case?
Or is there another way to do this easier?
I would really appreciate if you could help me.
Thank you very much in advance.
