These are the actual grades for 400+ individual students in the courses they took at a small, liberal-arts college in the midwest US. All the students graduated in 2006. Each row corresponds to a single student in a single course. The data have been de-identified by translating the student ID, the instructor ID, and the name of the department. Typically a graduating student has taken about 32 courses. As another form of de-identification, only half of the courses each student, selected randomly, are included. Only courses with 10 or more students enrolled were included.
data(College_grades)
A data frame with 6146 Grades for 443 students.

part of this sample.
iid Instructor ID
gradepoint A translation of the letter grade into a numerical scale. 4 is high.
Some letter grades are not counted in a student's gradepoint average. These have NA for
the gradepoint.
The data were helpfully provided by the registrar of the college with the proviso that the de-identification steps outlined above be performed.
