Results of midterm exam:
Mean score was 89.5%
S.D = 11.0%
Median = 91.9%
Highest score was 106.8%
There were a total of 79 points available (including extra credit).
Based on patterns of performance, question 51 was converted to extra credit,
making a total of 5 extra credit points.
Your percent score can be calculated by the formula:
100*(79 - X)/74
where X is the number of missed points.
If all answers, including all extra credit questions, are correct, then
X=0 and score would be 100*(79/74) = 106.8%
