Hi! I am quite new to Qualtrics, and I am stuck with the following problem:
For my study, participants should make pairwise ratings, meaning that they will make 3 rounds with 2 pictures each, that should be shown randomly. For example, in the first round, one participant sees picture 1 and 2, in the second round picture 3 and 4, and in the last round 5 and 6. For the next participant, this order could be 4 and 2, 5 and 1, and 3 and 6.
Every participant should see a random order, but should only see each picture once. Does anyone have an idea on how to do that?
Thank you in advance!
Question
pairwise combination of 6 pictures
