Answer Choice Randomization: Problem with randomized subset
I have the following problem:
I want to include 15 single-choice answers (3 groups / 5 answers possibilities per group) in one question and the respondent should get only 1 randomly chosen answer from each group - in total 3 answers.
I tried with the 'Advanced Randomization' function, but I just managed to create one 'Random Subset'. So I need to create several 'Random Subsets' in one question.
Do you have any idea how to create more than one subset or how to solve the problem in another way, so that the respondents just get one answer from each group? I struggle with the problem for hours. So I really hope you can help me.
Many thanks in advance,
