Description

Students develop skills both in statistical reasoning and statistical method by actively engaging in the practice of statistics as science. Students will study important current, psychological issues whose understanding requires a fundamental knowledge of statistical concepts, in particular, hypothesis testing and regression. Controversial topics will be chosen that are currently in the news and likely to remain so. Such psychological controversies are regularly found in journals and magazines such as American Psychologist and Current Directions in Psychological Science.

Reasoning in Psychology Using Statistics uses a classroom/laboratory approach for analysis of data, for hands-on production of data, and for simulation-based learning. According to Cobb (1993, p.4), "the lab approach accords with the movement of statistics back towards its roots in science, and with research in education that demonstrates the importance of active learning." Additionally, the classroom/lab setting allows students to access the vast array of data available through the Internet.

Reasoning in Psychology Using Statistics follows the guidelines developed by the American Statistical Association (ASA) and the Mathematical Association of America (MAA) which suggest that teachers should:


Textbooks (Very Optional)

Almost any introductory social science statistics textbook will be helpful. Here is one that I used to require:
Social Statistics for a Diverse Society
(3th edition) by Chava Frankfort-Nachmias & Anna Leon-Guerrero (Pine Forge Press, 2002).

The reason I no longer require a textbook is that there are so many free statistics resources on the web. A quick search on the search engine of your choice will probably bring new ones every day.
Here is a free statistics textbook.
Here is another.

If you learn best by listening, there are a number of podcasted introductory statistics courses. You don't need an iPod to listen to them. You can listen on any computer with speakers. Here is one from my alma mater, UC Berkeley.
MIT has a large number of courses with free content on all kinds of topics. Here are downloadable slides on introductory statistics.


Software

SPSS (Release 14.0) SPSS, Inc. - this software is available on the classroom computers and on most other campus lab computers. You do NOT have to purchase it for the class, however if you want a copy for your home computer, student versions are available at the student bookstores.

I will also use Microsoft Word and Microsoft Excel often and will sometimes give you Excel tools for statistics. If you don't have Microsoft Office, OpenOffice.org offers a FREE, high-quality office suite that is compatible with Microsoft Office. Althought OpenOffice uses a different format by default, you can save documents and spreadsheets in OpenOffice in the same format that Microsoft Office users use. A lot of free software is not very good. OpenOffice is a major exception. You can also try Google Docs and Spreadsheets for free.



Required Materials
"Clicker" or RF Response Card (How to get one). I explain how I use these in class in the "Attendence" section below.

Calculator:
I haven't used a hand calculator in years (I use Excel for everything.). However, most students will probably want to use a calculator for the course. Any reasonable calculator with a memory button will work. You are not permitted to use your cell phone's calculator on exams.


Attendence

You are expected to attend every lecture and participate through discussion and classwork. Lecture and lab attendance is NOT optional. All labs are in Room 13 in DeGarmo. Think of the labs as scheduled homework time with a tutor (your GA). If you do not attend a lab, you can still the submit lab assignments with a 10% penalty. Since labs are worth 5 points, the penalty is only half a percentage point of your final grade. Don't be fooled, though. Getting many small penalties add up quickly and often make the difference between 2 grades.

In lectures, from time to time, I will ask questions using the "Clicker" technology. You must give all your answers in good faith (i.e., no random or deliberately misleading responses). I will sometimes use your responses as data to illustrate data analysis. If the questions are about opinions or life history involving personal matters you will always have the option of clicking "I prefer not to answer this question." I will never look at any individual's response to these kinds of questions nor will I penalize anyone for choosing not to answer them.

Your class participation grade will be determined by the percentage of times that you participated using the Clickers. I will allow 2 unexcused absences before it affects the participation grade. You may make up classwork only if you were absent due to University sanctioned events, documented illnesses, or documented crises. Make-up assignments will typically be short essays.

Do not use an absent classmate's Clicker to make it seem that the student was in attendence. This is dishonest and will result in an automate failing grade for everyone involved in the activity.
 


Additional Notes

Make-up quizzes or exams/projects are typically not given. Special circumstances may result in reasonable substitutes for missed assignments.

The course contract is considered final. The work necessary to obtain the grade you desire has been outlined here. No additional work will be accepted to increase your grade. Do not come to me at semester's end asking if there is some additional work you can do to increase your grade. At semester's end, there is none.



If You Need Help...

Please visit me during my office hours with any questions you have. My job is to help you learn. If you need help, get it early; don't wait until you are "so lost I don't know what to ask!" If you cannot make it to my regular office hours then, please, make an appointment with me. Talk to me after class, call me (438-8410), or e-mail me at: wjschne@mail.ilstu.edu.

Evaluation

Your grade will be determined by weighting your performance on homework,article assignments, Mallard quizzes, in-class labs, 3 exams, and two projects. The grading scheme is not a curve. This is a good thing. This means that everyone can get an A if everyone performs well. Of course, this means that everyone could fail the course if everyone blows it off. A curve would make it so that only a certain percentage can receive high grades and that certain percentage would fail the course no matter how well they understand the material.

Each exam is worth a maximum of 150 points (3 Exams x 150 points = 450 total)
Each homework is worth 20 points (9 Homework assignments x 20 points = 180 total).
Each lab is worth 5 points (24 Labs x 5 points = 120 total).
The project is worth 150 points
Class Participation is worth 100 points

Therefore, there is a total of 1000 possible points. Your final semester grade is determined as follows:

                   
Performance        Grade
                     
900-1000            A
                      
800-899             B
                      
700-799             C
                      
600-699             D
                      
  0-599             F
