Generating item statistics from randomized pooled quiz sections

Brenda.D.7284

A question was posted over a year ago about this topic in the Community Corner, but I see no fix offered. I am hoping someone has a workaround for the lack of item statistics offered on randomized quizzes.

I have as many as 50 responses for items on my randomized, pooled quiz sections so I feel there should be a way to generate item statistics. I am only provided with the question average and the frequency each option was chosen in the detailed question statistics page, and NA for everything else. If the statistics feature does not generate these data, is there any way to set up a report to create discrimination index/point biserial for these items? Or even a way to set up the calculations using Excel?
