Max Diff Scaling - Frequently Asked Questions

Can I set up an experimental design - where the total items are larger than the items presented in a single screen?

Yes. You can set this up by limiting the number of attributes displayed. For example, if you have 10 attributes but wish to only display 5, you can set the Maximum Attributes to 5. Out of the 10 attributes, 5 attributes will be randomly choosen and displayed.
