Revised: November 2006
Descriptive statistics, exploratory data analysis, probability distributions, correlation, regression, estimation, and hypothesis testing. Three semester hours.
1. Acquaint students with the concepts of population and sample, and some of the
basic descriptive measures used to describe them.
2. Acquaint students with graphical methods for data presentation.
3. Introduce concepts of probability, random variables, and distributions.
4. Examine properties of common distributions, especially the normal and binomial.
5. Introduce the ideas of correlation and regression.
6. Provide an introduction to estimation and hypothesis testing by applying these procedures to population means and properties.
