The matrix and bipolar question types now work in NDSU's Qualtrics account. BUT... you must ensure that the Mobile-Friendly option is turned on to be able to publish your survey. The mobile friendly option is found in the format menu as seen in the picture below.
These question types were previously inactive in NDSU's Qualtrics account due to the fact that they did not meet the standards set forth in section 508 of the American's with Disabilities Act (ADA). Qualtrics has been actively working to make all of their question types meet these standards. We look forward to more question types becoming available in the future.
