Horizontal axis labels correspond to the midpoint value of a bin, which is 10 points wide. Here is the final exam statistical summary:
exam mean: 65 exam median: 69.5 standard deviation: 19.6 highest grade: 93 lowest grade: 24
Letter grades are based on the cumulative course average, which
is weighted according to:
homework (5 problem sets)---40%;
midterm exam---25%; and
the final exam---35%. This cumulative course average is then
converted into a letter grade according to the following
approximate numerical ranges:
A+ (92.5--100); A (87--92.5); A- (81.5--87); B+ (76--81.5); B (70.5--76);
B- (65--70.5); C+ (59.5--65); C (54--59.5); C- (50.5--54); D (47--50.5); F (0--47).
Here is the statistical summary of the distribution of
the cumulative course averages:
mean: 81.14
median: 82.23
standard deviation: 12.4
high: 97.1
low : 47.7
Here are the relevant final exam statistics.
