Section Description

The class will consist of a mixture of lecture, discussion, and projects to highlight particular topics. It would be impossible, however, for these to encompass all of the material for the course. There will be material in the text for which you will be responsible that we will not cover explicitly in class. I expect that you will read the material in the text before we discuss it in class. Key topics are: *Straight-Line Regression Analysis *The Correlation Coefficient and Regression Analysis *The Analysis of Variance (ANOVA) Table *Multiple Regression Analysis: General Considerations *Testing Hypothesis in Multiple Regression *Correlations: Multiple, Partial, and Multiple Partial *Confounding and Interaction *Regression Diagnostics *One-Way ANOVA *Two-Way ANOVA

Section Expectation

Students should expect three or more hours of work outside of class for every hour of class time. Reading the text for each class will be an ongoing homework assignment throughout the course. Homework assignments will be listed on the class webpage. Late assignments will not be accepted.


Final grades will be determined by exams/quizzes, homework, and participation in class discussions
