I'm a tutor for a university course that has just had a midterm exam marked and returned to the students. One of the students emailed me asking for summary statistics of the midterm exam: the maximum score, minimum score, and average score of the class. He says that in previous classes this information had been available, though I'm not exactly sure how he got it.
Is it normal for students to have this information? Am I obliged to give out this sort of summary data, or should I seek permission from the course coordinator first?
