PSY 221 - Elementary Statistics for the Behavioral Sciences
Five Quarter Hours

I. PREREQUISITES
Math 113 (Algebra) or 3 years of high school mathematics or placement. Students may not receive credit for both this course and MATH 251, PSY 121, or QBA 201.

II. COURSE DESCRIPTION
The aim of the course is to help you understand and conduct simple statistical procedures. Topics include central tendency, variability, correlation, sampling distributions, statistical inference, and simple tests of hypotheses.

III. TEXTBOOK AND SUPPLIES
Gravetter, F. J., and L. B. Wallnau, Statistics for the Behavioral Sciences, 5th ed., Wadsworth, 2000

...available from EdMap's distance-learning online bookstore.

IV. READINGS
The examination covers the following chapters of the textbook. To better prepare yourself for the examination, do the problems at the end of each chapter after you finish reading the chapter. The solutions for odd-numbered problems are given in Appendix C at the back of the book. If you need to refresh your basic math skills, see Appendix A.

You will be allowed three hours to complete the examination. The examination will be
administered in two parts:

Part I (Closed Book) The first part will be closed book and will assess your understanding of basic principles, your ability to compute simple statistical measures, your ability to interpret statistical results, and your knowledge of appropriate statistics to use for different purposes and with data at different levels of measurement. (A summary table of the tests covered in this course and the circumstances under which they are used is provided with this Information Sheet.) The questions on this part of the examination will be multiple choice and short answer. In order to leave yourself sufficient time to complete Part II of the examination, you are advised to complete Part I in approximately 45 minutes.

Part II (Open Book) When you hand in Part I, you will be given Part II. The second part of the examination will be open book. You will be able to use the textbook for this part. Part II will test your ability to use the various statistical procedures such as tests of significance, correlation, and regression. You will be expected to set up the statistical tests as illustrated in the “Independent-Measures t-Test” and “Repeated-Measures t-Test” pages which follow. A similar format should be used for other statistical tests of significance, although the specific information will vary with the type of test.

V. CALCULATOR
You may use a calculator for both parts of the examination; however, you may not use a programmable calculator (i.e., a calculator that can be programmed to calculate statistics such as standard deviations, etc.). If you do not have one, you should purchase an inexpensive calculator. It must have a square-root key and simple memory functions.

VI. GRADING CRITERIA
Your grade will be assigned on the basis of the percentage of the available points that you earn on the examination. The following scale will be used:
