Final Exam Results
-  The final exam consisted of 100 multiple choice questions and a perfect 
score is 100 out of 100. The raw score distribution for the class is 
as follows:  
 
- Median: 69
- Mean: 68.5
- Standard Deviation: 14.0
 
- The letter grade distribution is: 
 
- A: 83-100
- B: 69-82
- C: 55-68 
- D: 41-54
- E: 0-40
These grade ranges do not take into account +/- divisions, although these 
will be used for the final grades. For example, if you consistently fall 
near the low end of a letter distribution, you will probably receive a '-' 
and not a solid letter grade (e.g. B- rather than B). 
The distribution for the class is shown in the figure below.
