Reasonable Accommodations: Any student who has a disability that may prevent him or her from fully displaying his or her abilities in this course should contact me as soon as possible to discuss accommodations necessary to ensure full participation and facilitate your educational opportunities.

Basic Course Description: This is a course about experimental designs, requiring previous coverage of ANOVA from a models perspective. Also, you should be comfortable with matrix notation and have a basic understanding of matrix algebra. The course has two major components: major designs and hierarchical linear models. We will also discuss the logic of experimentation and causation in non-experimental designs.  In addition, we will touch on the analysis of time depended data.  

    The major designs considered are the completely randomized design, the randomized block design, the factorial design, the mixed design and the repeated measures design. You will be prepare for each design by reading, writing notes, and finding research examples. You will find an example of each design and bring them to class for class discussion. Make a copy of the article and bring it to class. As you consider each design you should keep in mind the description, layout, model, assumptions, efficiency, as well as advantages and disadvantages. Also, you will be required to turn in a written two-page summary and evaluation of the article. The evaluation should focus on the statistics and experimental design aspects of the research. In addition to these evaluations, you will be asked to run a number of data analyses using SAS and write a proposal involving a technique or design studied in class. 

Grade: In class mid-term (100), class projects (100), proposal and presentation (100), take-home Final (100).
