Weighting on Maxdiff project

I had the same question and got the response below, but also found a partial workaround.

• In short, you can’t weight Max Diff (or any other templated analysis in Qualtrics, as far as I can tell, e.g., Conjoint)
• But despite the ‘Weighting’ tab being hidden, you can still get to that page to create a weighting scheme — but you need to ‘create’ that link for yourself. So, go onto a ‘normal’ survey with recorded data, go to the Weighting page, and copy the URL into a Word doc or similar. Go to your Max Diff survey (on the survey editor page), and copy the survey code at the end of the URL (tips on how to do that below). Then replace the survey code in the Weighting URL you copied out first with the Max Diff survey code you want to create a weighting scheme for — then head to that new URL, and it will allow you to do so. You can then apply the weighting scheme you create to any Crosstabs you create (or Reports, etc.). But not the Max Diff itself, remember!

Example URL for the Weighting page

https://YOURORGNAMEHERE.SERVERLOCATIONHERE.qualtrics.com/weighting/#/surveys/SURVEYCODEHERE

Tip

You can get your survey code just by going to the survey editor and copying the long random string of characters at the end of the URL. It looks like Max Diff projects always start with ‘MD_’. Normal surveys seem to always start with ‘SV_’, in comparison.

Hope that helps?!

Original response from Qualtrics, May 31 ‘24

Currently, Weighting is not an available feature for MaxDiff Projects within the platform.

MaxDiff Analysis is based on a custom statistical model derived from collected responses, and this model is independent of the Response Weighting System, making the two incompatible.

 

However, it is possible to use the Export feature in the MaxDiff Report tab to export each segment's individual preference shares or individual utilities.

Weighting can then be manually applied using tools like Excel.

 

I understand that this manual process may not be straightforward, but unfortunately, at this time, weights cannot be directly integrated with MaxDiff Projects.

gregsimmonds thank you very much, I will try this way!!
