## This page contains a summary of the results of the Physics 5B midterm and final exams for the Winter, 2009 academic quarter at the University of California, Santa Cruz.

## FINAL EXAM (Thursday March 19, 2009)

The final exam and its solutions can be found on the Physics 5B website. Graded tests can be picked up in my office starting on Monday March 23. Here are the relevant exam statistics. First, a histogram of the test scores is shown below:Horizontal axis labels correspond to the upper value of a bin which is 10 grades points wide. For example, the 170 label refers to grades from 161--170, the 160 label refers to grades from 151--160, etc. The total number of points available was 175. Here is the final exam statistical summary:

exam mean: 107 exam median: 108 highest grade: 167 lowest nonzero grade: 45

Approximate grade equivalents of the test scores: A+ (163--175); A (149--162); A- (135--148); B+ (121--134); B (107--120); B- (93--106); C+ (79--92); C(65--78); D(51--64), F (0--50). Keep in mind that the grade equivalents apply only to this exam, and take into account the distribution of final exam scores. The distribution of the grade equivalents for the final exam is shown below.

## MIDTERM EXAM #2 (Friday February 27, 2009)

The second midterm exam and its solutions can be found on the Physics 5B website. Here are the relevant statistics. First, a histogram of the test scores is shown below:with a standard deviation of 16. Horizontal axis labels correspond to the upper value of a bin which is 5 grades points wide. For example, the 95 label refers to grades from 90.1--95, the 90 label refers to grades from 85.1--90, etc. The total number of points available was 100. Here is the midterm exam statistical summary:

exam mean: 57 exam median: 55 high grade: 100 low grade: 14

Approximate grade equivalents of the test scores: A+ (92--100); A (84--91.9); A- (76--83.9); B+ (68--75.9); B (60--67.9); B- (52--59.9); C+ (44--51.9); C(36--43.9); D(28--35.9); F (0--27.9). Keep in mind that the grade equivalents apply only to this exam, and take into account the distribution of midterm exam scores. The distribution of the grade equivalents for the midterm exam is shown below.

## MIDTERM EXAM #1 (Friday January 30, 2009)

The first midterm exam and its solutions can be found on the Physics 5B website. Here are the relevant statistics. First, a histogram of the test scores is shown below:with a standard deviation of 17.6. Horizontal axis labels correspond to the upper value of a bin which is 5 grades points wide. For example, the 95 label refers to grades from 90.1--95, the 90 label refers to grades from 85.1--90, etc. The total number of points available was 100. Here is the midterm exam statistical summary:

exam mean: 60 exam median: 62.5 high grade: 97.5 low grade: 5

Approximate grade equivalents of the test scores: A+ (94--100); A (86--93.5); A- (78--85.5); B+ (70--77.5); B (62--69.5); B- (54--61.5); C+ (46--53.5); C(38--45.5); D(30--37.5); F (0--29.5). Keep in mind that the grade equivalents apply only to this exam, and take into account the distribution of midterm exam scores. The distribution of the grade equivalents for the midterm exam is shown below.
