Quiz 4 Results

Each quiz normally consists of 50 multiple choice questions and a perfect score is 50 out of 50. The raw score distribution for the class is as follows:: Median: 34.5; Mean: 33.7; Standard Deviation: 7.7
Here is the conversion between letter grade and raw score:: A: 42-50; B: 35-41; C: 28-34; D: 22-27; E: 0-21

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.
