# CSE 121 Fa 2000 -- Midterm Statistics

The following graph gives the grade distribution. Each column is the count of the number of students receiving a grade that falls into the bucket. Each bucket (except for the rightmost) has a 5 point range, so if the label is 10, that means that the column counts the number of scores in the range 10*5 = 50 to 10*5+4 = 54 points.

The midterm grades were a little low, but all students were graded uniformly, so should be fair. Talk to me if you think you deserve more partial credit points. The mean is approximately a B+ grade.
