This idea has been developed and deployed to Canvas
Here is my idea.
The Quiz Statistics function currently supports up to 100 questions per quiz. For a quiz that has more than 100 questions, the analytic tool would stop working. I have spent hours to figure out this limitation.
Please lift the limit to 200 or more and put a note of the limitation.
The visualized report is different from the one (Item Analysis) that I have to download to Excel. There is NO Discrimination Index in the downloaded Excel file.
