Better late than never

Ok, I've put solutions to the last two homeworks (10 and 11) on the I-drive. They are Microsoft Word documents (Office 97 compatible).

I do not have the technology to convert them to pdf's on my home computer. I hope you can read these. When I get to the office I'll convert them to pdfs.

Good luck. See you all this afternoon.

approximate grade distribution at 3/4 point

Here is the distribution of scores that was distributed in class and posted on the I-drive. There are some variations in consistency due to some changes in some people's grades since the report. This is designed to be approximate. Those close to the cutoff points should be careful interpreting their grade. If you are near a breaking point you need to make sure you get the right signal: do well on the final to shore up the higher grade.

This is in percentage terms since some people have different divisors on their total points.

average = 73.21%
standard deviation = 11%

A: 84.5 and higher
B: 73.5 - 84.49
C: 63.0 - 73.49
D: 50.0 - 62.99
E: which is F (At Ohio State we got Es, not Fs) is below 50%

Some of you will find that your grade is lower than what this scale suggests. You should consider your grade adjusted upward. But keep in mind, these "grades" are not relevant. The scores are relevant. I know its hard for you to think in this manner that although you can say you have a B going into the final, from my perspective you have a point value going into the final. Why? Because at this point all B's are not the same. And the final distribution will change. So to me, the grade has less meaning. It is merely a guideline.

Moreover, you should keep in mind that this is as open and fair of a scaling as you will find at IUP. I'm trying to make sure you have as much information as possible. And before you complain, please notice that with a class size of nearly 100 (a few people are not listed on this due to oddities in the points which they should understand and not for the rest of you to worry about), there are only three scores in the failing range at this point (and one of those I know is incorrect and is much higher so there really are only two failings, not including those who had given up and stopped earning points and for some reason decided not to withdrawal). That's a collective job well done, folks. You're doing well. Keep it up!

Good luck.

Uh yeah, i'm slow

I haven't been able to get the solutions of the last two homeworks and the grade distribution out there as I said I would.

I'll get them out there when I get to the office on Wednesday. I just won't consider it tragic. We went over it all anyway.

Update you again later.

Office Hours update

For the remainder of the week, I have office hours Wednesday 12:45 - 2:45. Thursday by appointment only. I will not be in the office on Friday.

Answer Key to Final Exam sample problems

Here's a key that I got from one of your classmates. I decided to use it instead because I'm lazy. ;-) Do you think it is correct? Let me know.

Sorry for all the monopolistic competition questions. You won't have many at all, however, (here's some free info for those who pay attention to these blogs) the written problem is related to monopolistic competition. It will be a game theory problem applied to choosing whether or not to advertise a product. ;-)
