TEXT:
Howell, D.C. (1997). Statistical Methods for Psychology (4th ed). Belmont, CA: Duxbury.

OBJECTIVES:
This course is designed to enrich the student's knowledge and understanding of the statistical method as it pertains to the design and analysis of experiments in the behavioral sciences. Specifically, at the end of the semester a student should be able to read and intelligently assess most of the research literature in his or her own particular field. The student will learn to recognize and understand the common themes that reoccur throughout the variety of designs presented. Also, at the end of the semester, a student should be able to apply the statistical designs presented in the course to his or her own research studies.

REQUIREMENT:
A ten-digit scientific calculator.

EVALUATION:
The course grade will be based on three components: a mid-term examination, a final examination, and written hand-in assignments. The examinations will consist of problems and short-answer questions designed to tap both computational and conceptual skills. The examinations are open-book and open-note. The weighting of the three components will be as follows: mid-term examination, 30%; final examination, 40%; and assignments, 30%. Classroom attendance is mandatory except for emergency situations.

TOPICS:

  1. Simple randomized design (one-way ANOVA) and multiple comparisons.
  2. Factorial design (two-way ANOVA).
  3. Simple repeated measures design including both additive and nonadditive models.
  4. Randomized blocks design.
  5. Factorial design (three-way ANOVA) and generalization to higher order designs.
  6. Latin square type designs and confounding problems.
  7. Analysis of Covariance (ANCOVA).
  8. Miscellaneous designs including a variety with combinations of between-subject and within-subject factors.
