Exam and grade related stuff
- Your final grades are in. (Sorry abou the confusion but it is updated on 5/8, 11 a.m.) The grading scheme is as follows: A = 90-100, B+ = 87-89, B = 80-86, C+ = 77-79, C = 70-76, D = 60-69, F = 0-59. You can pick up your exam at the math office in Wilson.
- Have a good summer!
- Check your grades and make sure I recorded correctly. ID numbers correspond to the last four digits of your ID numbers. I did not convert all quiz scores into 100 pts. (Although they are shown in the table.) The bold face indicates the score that was dropped from your total score. If you want me to change the one you want to drop, let me know. (updated on 4/28)
- The third and last exam will be on 5/7 (10:00 - 11:50). It covers one-way ANOVA and two-way ANOVA only.
- For the second exam on 4/2:
- Practice exams can be found at cards and copies (sorry I didn't get the files this time).
- solutions
- Equation list for the exam.
