To gain an understanding of why and when one would use multivariate statistical methods, including multivariate analysis of variance, factor analysis, and meta-analysis. 2. To develop skills in reading journal articles that present applications of multivariate methods or advances in multivariate methods, e.g., articles in Psychological Bulletin (formerly) and Psychological Methods (currently). 3. To develop skills in using computers to analyze multivariate data, to be able to interpret printouts, and to be able to write up the results for a journal article. 4. To gain a basic (not necessarily advanced) understanding of the theoretical rationale and derivations for multivariate statistics. 3 REFERENCES Journal Articles to Be Read in This Course (e-reserve) Algina, J., & Keselman, H.

Where to take complaints about a Teaching Assistant or Course Instructor Occasionally a student may have a complaint about a T.A. or course instructor. If that happens, you should feel free to discuss the matter directly with the T.A. or instructor. If the complaint is about the T.A. and you do not feel comfortable discussing it with him/her, you should discuss it with the course instructor. If you do not feel the instructor has resolved the matter to your satisfaction, then you should speak to the Department Chair, Professor Chuck Snowdon (room 238 Psychology). You should also speak to him if the complaint is about the instructor and you do not feel comfortable discussing it directly with him/her. If you believe the T.A. or course instructor has discriminated against you because of your religion, race, gender, sexual orientation, or ethnic background, you also may take your complaint to the Affirmative Action Office (room 175 Bascom Hall). If your complaint has to do with sexual harassment, you may also take your complaint to Ms. Arlene Davenport, the Psychology Department sexual harassment contact person. multiisyl.f03.wpd 6
