• Here is how the class performed on Exam 3:
  
  • Mean = 79% on MC section (compared to 67% on Exam 1, and 68% on Exam 2)
    
  • High = 96% on MC section (compared to 84% on Exam 1 and 86% on Exam 2)
    
  • Low = 50% (Random guessing = 27%)
    
  • Std. Dev. = 11%
    
• If you filled in your PID on the Scantron form, you should be able to access your MC score via the ONYEN or Student Central websites.
• Answers:  B, C, B, A, C, A, A, B, D, A, C, C, A, B, D, C, B, D, D, C, A, A, A, B, A, D, C, C
• If you accidently filled in the wrong bubble on your answer sheet, and you wrote sufficient justification for the correct answer on your test papers, then write a note to this effect on the top of your exam so that you can get credit for your explanation.
• Because the class average was what I expected, I will not have you submit your test corrections for extra credit as on the previous two exams.  However, I still encourage you to review this exam on your own or with someone else as you prepare for the final exam.
