Refactoring the generation of quiz question statistics into its own gem.
This patch adds support for Essay question statistics.
Closes CNVS-12725
TEST PLAN
---- ----
- create a quiz with an essay question
- perform an API request to retrieve the quiz statistics
- ensure that the following metrics are generated and correct:
- "graded": number of students whose answers have been graded by the
teacher
- "full_credit": number of students who received a full score
- "point_distribution": a list of scores and the number of students
who received them (so if 2 students got graded for 3 points, it
should have a key of 2 and a value of 3), un-graded submissions
should be keyed under null
- "responses": number of students who answered the question
(wrote anything)
- "user_ids": IDs of those students
- documentation for QuizStatistics -> Essay should be updated with the
new stats
> Other things to test
- verify that the old statistics page still renders:
/courses/:course_id/quizzes/:quiz_id/statistics
- verify that you can still generate both student and item analysis
CSV reports
API endpoint for quiz stats:
/api/v1/courses/:courseid/quizzes/:quiz_id/statistics [GET]
