(a) The distribution of the number of failed courses of students. (b) The distribution of the number of terms that students have failed courses. (c) The distribution of the ratio of the number of failed courses to the corresponding number of courses for each student.

(e)–(i) The heights of bars represent the average levels for these indicators. Error bars (black) show the 95 percent confidence intervals of mean estimation. The blue bars labeled by ‘yes’ represent failed students and the orange bars labeled by ‘no’ represent non-failed students
