Home Page for Physics 171 (General Relativity) for the 2015 Fall Quarter

Final grades for Physics 171 have been assigned. The distribution of all the final course grades is shown below:

course grade distribution

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. A histogram of the test scores is shown below:

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

You can pick up your graded final exams in my office any time after 2 pm on Thursday December 10.
