I'm looking for item analysis for a quiz I gave last school year. Since most my students graduated, the sample size is 6, hardly sufficient for good analysis.
Where is that data? Can I access it?
Interesting that only 6 students are there. I'm guessing that means that your school system has been deleting student accounts from Canvas after they graduate. When I advice admins I usually suggest they keep students on the system for many years after they leave. There are ways to mark them as Concluded so that they can't access the system any more, but for things like grade retention it's sure nice to still have them in the system.
At any rate, I believe the Item Analysis stats are generated on the fly when you access them. So if the students are no longer in Canvas I don't think you are going to be able to get those stats. But, it might be worth clicking the Help button and Report a Problem to see if Canvas Support can work some magic. There is a chance that the data may still be there and be retrievable in some other manner.
