Grades

The following table shows the grades of students who supplied the instructor with 3- or 4-digit identification numbers for the purpose of posting grades anonymously. It was last updated on June 11.

The records are listed in alphabetical order by identification number. The mean, median, and average deviation values reflect the grades of all students, not just those whose grades are shown. The mean grade for each assignment is computed by converting the letter grades to numbers according to the following scale, averaging the numbers, and converting the resulting numbers back to letter grades according to the following scale:

The average-deviation figure is in letter-grade increments. For example, an average deviation of 1.0 means that on average, individual students grades were exactly a letter grade above or below the mean grade. Average deviation is essentially a measure of how widely distributed students grades are, as opposed to being clustered together at the mean.
