Instructors can hide the box and whisker plot (grade distribution) graphs to keep students from viewing the summary statistics of the class and figuring out each others' grades. By default, the whisker graph is on. When the grade distribution graph is hidden, students cannot view any aspect of the graph, including the high, low, and mean scores.

Note: The grade distribution graph displays for students after five or more students submit the assignment and remains visible for instructors after hiding the graph from students.
