Update on the 610 test situation

First of all thank you for the many emails and instant messages that encouraged me to pursue this. While it is depressing that this situation has arisen, I am encouraged by the fact that so many of you are concerned about it and think that it is wrong.

Unfortunately the issue has not resolved itself. The parties did not come forward. So after further attempts to figure out how this could possibly have happened at random failed, I decided to fall back on statistics.

This afternoon we entered all of the multiple choice answers for everyone who took the same form as the questionable tests (and gee that was fun!--NOT). Once this was done, a correlation matrix was calculated. Because the scores are not normally distributed I will report the median rather than the mean. The median correlation was about a .27 with a standard error of about .07. The highest? Above a .96 on the exams in question. This more or less convinced me there is a problem.

After these calculations, I notified Dr. Peterson and Dean Fischer. We will meet soon to discuss the next steps in the process.

I will keep you informed.

Thanks for your patience on this important matter. Remember it is more important to get it right than to act quickly.

MBA 610 tests are corrected

Well they are done. :)

I will give you all of the details in class, but overall they were pretty good :)

I do have a few concerns however. Namely it was suggested to me that there may have been cheating on the exam.

Thus, a few comments:

1. I will "up the bounty" on evidence. There will now be a 200 point reward.
2. I am entering the actual answers of students to look for extremely high correlations of answers. However, just eyeballing it, it appears that there may be a problem with a couple of students.
3. If you turn yourself in, the punishment will be much less severe.

You have to understand, I do not want to believe that anyone cheated. My prior belief is that you are innocent. However, if I am able to prove that cheating occurred, then I will be left with no choice but to take it to the Dean and the VP of academic affairs. This will force you to retake the class (which will really screw up some of your job plans!).

So, if you did cheat, please come forward. I will be much less harsh on those who self-report.

(I learned that from the NCAA ;) )
