  • A score distribution graph would be nice.
  • Number of attempts, and percent completed.
  • Some item analysis - discrimination index, and easiest/hardest question?

Could copy some stuff from the blackboard analysis tool.

Show frequencies of the following break-downs:

  • completion status
  • pass/fail
  • number of questions attempted

Can you delegate this to me? I can work on adding a score distribution graph and the number of attempts and percent completed.

Hi,
Thanks for offering to help. I won't assign this issue to you because I don't know who you are, but I'm interested to see what you come up with. Please make a pull request once you've written some code.

heatmap of question scores in attempt list
helps with #3

To achieve this, info on question scores per attempt is now saved in
AttemptQuestionScore objects. I added that model a while ago but didn't
use it because I couldn't work out how to keep it up to date.

Now, these objects are set whenever a cmi.objectives.N.score.X SCORM
element is saved, or when a RemarkPart or DiscountPart object is saved
or deleted.

They're created on-demand for old attempts, so I don't have to run an
enormous DB migration.
