Text: Hays, W. L. (1994) Statistics. 5th Ed. Harcourt Brace.

There will be readings for each class period (please read these materials before the relevant lecture) from both the text and supplemental journal articles. In addition, a project, based on the material covered in the previous lecture, will be due at the beginning of each new class. We will review the project at the beginning of class and then cover new material week.

Projects

There will be up to 10 computer assignments that will count for 40% of the course grade. Projects and due dates will be announced in class. Each assignment will be worth 10 points if handed in on time, 5 points if handed in by the next class period, and no credit thereafter. Discussion of these projects will constitute much of the course content. The project data and descriptions will be available on my homepage. You will need to copy this data to your computer and then place it in a statistical software package. DO NOT EDIT THE ORIGINAL DATA FILES IN MY DIRECTORY!

Final Exam

The remaining 60% of the course grade will be based on a comprehensive final exam.
