Applied statistics using SAS --- Prof. Stanley Sawyer (SAS is a widely-used statistical package)

**Topics covered:**

Prerequisites: | Math 3200 and Math 493 or permission of the instructor. Math 493 may be taken concurrently. |

Time and Location: |
Tues,Thurs 11:30AM-1:00pm
--- Lopata Hall Rm 103( Note: (08/27/2010) Construction in Lopata has made finding
our classroom like an exercise in Dungeons and Dragons, only without the
Dragons.To find Lopata 103, enter Lopata Hall through the 2nd floor entrance
off the courtyard formed by Cupples I, Dunker, Sever, and Lopata
Halls.DO NOT enter the 3rd floor entrance (in the arch between Sever and Lopata Halls) AND DO NOT ENTER the 1st floor entrance into the Lopata common room with the food court, on the same level as the 1st floor of the Physics buildings. When you enter the 2nd floor entrance, turn immediately right, turn right again into a staircase and go DOWN one flight of stairs. Follow the hallway to Lopata 103. (This hallway goes nowhere else, and in particular you cannot get to this room in any other way.) |

**EXAMS, HOMEWORK SETS, AND GRADES:**

There will be four homework sets, an in-class midterm on **Tuesday,
October 19**, and a takehome final. Grades will be based on the
homework sets (around 50%), on the midterm (around 20%), and on the
takehome final (around 30%). The takehome final will be due on or before
**Monday, December 20**. Cr means D or better if you elect ``Credit/No
Credit.''

**COLLABORATION:**

Collaboration on homework is allowed and can be helpful (and fun).
Collaboration on homework is encouraged, both for using the computer and
for doing problems. However, you must do all written work by yourself,
both computer programs and answers to homework questions. You must also
write, enter, and run all programs yourself.

**If you collaborate** with someone on a homework, **list his or her
name** in a note at the top of the first page of your homework.

**COLLABORATION ON TAKEHOME TESTS:**

There should be NO COLLABORATION on takehome tests, other than for the
mechanics of using the computer.

**WARNING:**

Make a copy of each homework before you hand it in !!

It may not be returned before you need to refer to it for the next
homework (or for the next test).

**HOMEWORK AND TEST PROBLEMS:**

If a problem asks you to do a statistical test, EXPLAIN CLEARLY what the
problem is and what your answer is. Your answer should include what the
null hypothesis H_0 is, what test you used, what the implicit
alternative H_1 is for this test, what the P-value is, and whether
the data is significant, highly significant, or neither for this
hypothesis and test. If you use SAS or a comparable computer program, hand
in your homework in the format described below.

**ASSIGNMENTS USING SAS (OR OTHER COMPUTER PROGRAMS):**

If you use SAS to do a homework problem, then the SAS program and
output MUST BE INCLUDED as part of the assignment.

ALWAYS INCLUDE YOUR NAME in a `title` statement in your SAS
programs, so that your name will appear at the top of each output page.

ALL HOMEWORKS MUST BE ORGANIZED in the following order:

(**Part 1**) First, your answers to all the problems in the homework,
whether you use SAS for that problem or not. If the problem asks you to
generate a graph or table, refer to the graph or table by page number in
the SAS output (see below). Xeroxing a page or two from the SAS output or
cutting and pasting into a Word file or TeX source file is also OK, but
forward references by page number will usually be sufficient.

(**Part 2**) Second, all SAS programs that you used to obtain the
output for any of the problems. If possible, similar problems should be
done with the same SAS program. (In other words, write one SAS program for
several problems if that makes things easier. Better yet would be one SAS
program for the entire homework with appropriate `title` or
`title2` statements to separate the problems in your output.)

(**Part 3**) Third, all output for all the SAS programs in the
previous step.

NOTE: If an answer in Part 1 requires a table or a scatterplot that you
need to refer to, make sure that your SAS output has overall increasing
(unique) page numbers and make references to Part 3 by page number,
such as ``The scatterplot for Problem 2 part (b) is on
page #X in the SAS output below.''

MAKE SURE that the page numbers in your SAS output has increasing page
numbers. If you do the entire homework in one SAS file, SAS will provide
increasing page numbers in the output. DO NOT say, ``see Page 3 in
the SAS output'' if Part 3 has output from several SAS runs, each of
which has its own Page 3. In that case, you can either write your own
(consecutive, increasing) page numbers on the SAS output, or else (for
example) refer to ``Page 2-7 in the SAS output'' (for page 7 in
the second set of SAS output) and write page numbers in the format ``2-7''
at the top of pages in your output. Remember that if I can't find your SAS
output for a particular question, I can't give you as much partial credit!

SAS programs should be structured, or have enough comments, so that
someone who looks at the program a year from now can easily tell what the
program is doing. It is even better if descriptive comments can be put in
`title` (or `title2` or `title3`) statements, since
these will appear in the SAS output as well as in the SAS program. SAS
programs may be graded for understandability.
