M 5/24/04

The scores for your Chapter
13 test are complete. The last student took this test on 5/17/2004. The
5number summary, omitting one “outlier” score far below the rest of the
scores, is as follows:
Low score = 50
25th percentile = 65
Median = 75
75th percentile = 81
High score = 100
Again omitting the outlier, the mean score was 74.4, which compares well with
the mean of 73.8 on the Chapter 11 test.
For comparison purposes, the 5number summary for the Chapter 11 test was as
follows (with no outliers):
60
66
74
81
93
One could summarize the differences between the two tests by saying that the overall
distribution of scores was almost identical, with the exception of a few very
high and a few very low scores on the Chapter 13 test. However, one
interesting difference that can be seen only when looking at the classes
separately is that on the Chapter 11 test, B period’s median score was 5
points higher than A period’s median score. On the Chapter 13 test, the
situation was reversed, with A period’s median score 6½ points higher than B
period’s median score.

email address for Jeremiah or J.P., please let me know.


T 5/25/04

I finally have your Chapter
12 tests finished now, too. Many of you saw your scores from the multiple
choice test (Part 1) earlier, but now the free response test (Part 2) is also
graded. Remember, this is the test on which I said I would count only the
better half in your average.
Out of 30 students, 24 scored higher on Part 2. The median score on Part 1
was 73% (C), and the median score on Part 2 was 88.5% (B+). Surprising? Remember,
students tend to have a lot of trouble with multiple choice questions in
mathematics. Since more than half of your final exam on Thursday is
Always/Sometimes/Never and multiple choice, you will need to work carefully
through those portions of the exam. Do not rush.
There were 5 students who scored 99, 100, or 101. Here is the 5number
summary for the Chapter 12 scores that were recorded (i.e., maximum of Part 1
and Part 2):
40
76.5
88.5
95
101
Please check your email for your personal score report. If anyone has an
email address for Jeremiah or J.P., please let me know. All tests will be
available to be picked up tomorrow, beginning at about 10:00 a.m.


W 5/26/04

Optional Chapter 1213 test
pickup, beginning at 10:00 a.m. You may also pick up your tests during the
review session.
Optional review session, Room R,
beginning at 10:30 a.m. The session will last up to 3 hours (i.e., until
1:30 p.m.) if there are any students still there. Come for as much or as
little as you wish. People will be filtering in and out of the room (quietly)
the whole time. Food and beverages will be permitted, as long as you clean up
after yourself.
This session is open to students from any section of geometry. Invite your
friends!
Please note that I have added some coordinate
geometry proof examples to the Review
Problem Compendium, as well as a copy of the exact formula sheet that you will be provided with
on the exam. There is even a draft format
description that shows the weights of the various portions of the exam,
so that you will know what to expect.


Th 5/27/04

Final Exam, 2:00–4:00 p.m., Trapier Theater. Bring several sharpened pencils with erasers, plus
a straightedge if you wish. A compass is permitted but not required. Do not bring
paper or notes, since any scratch paper you bring with you will be
confiscated before the test. No calculator is allowed for my students.
Regardless of what the calculator policy may be for the other sections of
geometry, no calculator is allowed on the exam for A and B period students.
Accordingly, you will be granted more leeway regarding the form in which you
leave your answers. An algebraic form that is not fully simplified to a
single decimal result will be acceptable.
The most common area and volume formulas will be provided for you in a formula sheet. If there are any other
formulas you think you might need, such as the quadratic formula or the Power
Theorems, you should memorize those before the exam.
