You can view the grades for a specific assignment by clicking on the class average for that assignment on the main course page.
This page gives you several different breakdowns of grades, first you have the overall statistics on the assignment. The table will tell you how many students participated, the median score, the class average, all Quest users average on the assignment (this is calculated off of all Quest users average on each question), the average points earned on the assignment, and the standard deviation for the assignment.
The MEC Analysis shows how many students selected each answer choice for multiple choice questions. The gray rows are not a multiple choice questions and questions with fewer options will just show zeros for the additional choice columns. This can provide information about what distractors are being chosen the most frequently to readdress common mistakes with the class.
The bottom graph is the response time distribution for the assignment, which provides insight as to when students submitted the assignment. Hovering over the peaks provides a pop-out with more details about that submission.
