Is it possible to limit quiz question statistics to the last attempt? We often run quizes in which we allow students multiple attempts, but we really only care about their responses on the last attempt. In particular, to judge how a large class has fared on each question, it's useful to go to the statistics for each question, which has a table showing the number of responses for each answer choice. (As an aside, a histogram of this data would be much more useful.) In this case, you really only want to see the last responses of the students.
Thanks in advance for your replies,
