I want to compare 20 items with each other to know at the end which items are most important for the respondents. To do this, I like to show participants always 4 of these 20 items (random) and let them pick the MOST and LEAST important one. At this moment, I have used the question type ‘Grouping Closed Card Sort’. Unfortunately, it’s only possible to show all the items at once or only one.
Beside, I would also like to repeat this question 10 times for each respondent, each time with a random set of 4 items. However, at the end, all the items should have been showed just as often as all the others.
Can anyone help me?
Thanks in advance!
