Craig Lecture MidTerm #1 Results
The MidTerm #1 Solutoin Key can be examined online.
Updated (Thursday, Feb. 19 9:05 am): We forgot to update scores for the fact that we dropped 1 multiple choice question from grading. Everyone's score in the database went up by 1.5 points.
The 120 people who took the first Astronomy 104 midterm got an average score of 39.1/50 (corresponding to a B-) with a standard deviation of 5.9. The high score was 50/50 and the low score was 22/50.
To access your scores, enter your modified Dragon ID (MDI). Your MDI consists of the last 4 digits of your Dragon ID plus the middle initial of your name (if available). Try first with the middle initial. If your score doesn't come up, try just the last 4 digits of your Dragon ID. If it still doesn't come up, check with your lecturer.
The distribution of scores are shown in the plots below:
