I'm looking to use a Qualtrics survey to perform what will end up being a massive number of pairwise comparisons. I have 300 visual stimuli, I need to have participants rate the visual similarity between all possible pairs of those stimuli. That's roughly 45,000 pairs. Each participant will rate roughly 300 or so of these pairs. 15 participants for every pair. The issue is how to have Qualtrics generate the pairs in its interface (obviously, I don't want to do this manually). Is there a way to create a gallery and have Qualtrics draw from it in an ordered fashion, to form all possible combinations? Additionally: Can this be done in sets of 300? Any help at all would be appreciated. I have little experience with coding or scripts but would be happy to learn.
