Article Review #2

The next article review is due Friday, November 3, 2006.

I neglected to bring the handout to class today (Friday), however I announced the assignment was already posted on the I-drive. So you can go to the I-drive to get the assignment as well as the reading.

I hope to remember to bring the handouts to class on Monday.

Have a great weekend.

An exerpt from an IM regarding homework #8

CinciDood: You do have enough info...
CinciDood: here's some hints.
CinciDood: for the first one, here's what you need to do...
CinciDood: you need to find NS...
CinciDood: you can do that from I = NS + KI
CinciDood: you have I and you have the info to find KI
CinciDood: so, find NS
CinciDood: then you use NS = Sp + Sg
CinciDood: since you are given Sg, and you just solved for NS,
CinciDood: you can now find Sp
CinciDood: think of these as little puzzles.

Midterm Update

Here is some information in advance of the return of the second test. I've tabulated scores from the test and also have tabulated scores for the first half of the semester.

Test 2 distribution:

mean = 31.2125 out of 45 (69.36%)
median = 31 out of 45 (68.89%)

standard deviation = 5.22 (11.61%)

The distribution of "approximate grades" is as follows:

out of 45 points:

A: 36+ (17 observations)
B: 31 - 35 (28 observations)
C: 27 - 30 (23 observations)
D: 23 - 25 (6 observations)
F: 22 and lower (6 observations)

**************************************************************************

Midterm grades:

From your scores on the tests and homework assignments, you can compute a weighted average. If you scored perfect on all assignments you could have up to 46 points. So calculate your weighted average and divide by 46 to get your current percentage score. Currently the distribution is as follows:

mean = 71.76%
median = 72.01%
stdev = 11.60%

So the following distribution of "approximate grades" is used to determine the midterm grade:

A: 82.7% and higher (11 observations)
B: 71.1 - 82.6% (34 observations)
C: 59.5 - 71.0% (23 observations)
D: 50 - 59.4% (10 observations)
F: below 50% (2 observations)

************************************************************************

I am required to post a midterm grade for all of those in the D and F range. If you do not get a midterm grade you are considered to be in good standing (C or better).

I will return the exams on Friday. I will report to you your weighted average and your pecentage score, along with your expected grade.

Test #2 review information

I've reorganized the I-drive folder a little bit.

You should find more recent, pertinent documents in the folder and the older documents moved to an archive folder.

On the I-drive you can now find sample multiple-choice problems for Test #2. I've included the review sheet that was distributed in class this morning. There are also suggested solutions to some of the homeworks since the first test.

The answer key for the sample test will be posted on this blog sometime Tuesday.

There is a newer document entitled "How to do well in Econ 121". You should read it to make sure you're doing what you need to be doing.

Reminder: I repeatedly suggest you to read the text. It is a very useful exercise to read the chapters carefully. If you are one of those who claim that a text is a "waste" then you do not know how to learn as much as you possibly can. Lectures, discussion, and readings are the traditional, and well-accepted methodology of higher education. Welcome to the academy, folks. Learn to work the system to your benefit.

If you were NOT in class today, Monday, to get the review sheet, you should get a copy from the I-drive. Be aware of the classroom seating guidelines for this and future test days.

Good luck.

Homework #7

Due to some issues, the homework assignment can't be posted on the I-drive. If you need a copy of the handout you should stop by my office during on Tuesday.

Please note: Tuesday office hours will run 10:30 - 11:30 and 2:30 - 3:00 on Tuesday. I have to reschedule the 11:30 - noon half-hour due to a lunch meeting.

Stay tuned for any updates and hints.

On the behavioral economics study of Zoë's

From Zoë Thorkildsen:

*****************************************************************************

Hi,

I was wondering if you would be willing to announce to the class
section I already recruited from (Julian 10:30 MWF, Potts 1:45 TR,
Sissoko 10:30 MWF) that I am now recruiting for participation on
October 16th at 5:15pm. Anyone who is interested in participating
should email me (zsvk@iup.edu) with their name and banner ID #, and I
will sign them up for participation.

Just in case you want to remind them, the experiment will consist of
participating in a simple decision making task, and should take
approximately one hour, no more than an hour and a half at the most.
They will be paid $5 for showing up, and have the opportunity to earn
up to $30 during the experiment, to be paid in cash as they leave.

Thank you all again for your help with this!
-Zoë

On Homework 6

To answer the second problem you will need to make use of that formula that we used to derive the GDP deflator.

Recall the formula for the deflator:

GDP deflator = (nominal GDP / real GDP) x 100

So, using algebra you can solve for real GDP as:

real GDP = (nominal GDP / GDP deflator) x 100.

I hope that helps.

For anyone checking this to see if there was a homework assignment, I'm sorry I did not put a copy of this assignment on my I-drive. Unfortunately I'm no longer at the office today so I won't be able to post the handout there until I get into the office Tuesday a.m. I'm sorry for the inconvenience.
