**Course Description**: Organizing, displaying and summarizing data. Inference based on elementary probability models including estimation and hypothesis testing. Faculty of Science credit will not be given. Credit will be given for only one of Statistics 203 and Statistics 200. Students who have taken Mathematics 100 are advised to take Statistics 200 rather than Statistics 203.

**Prerequisites**: Mathematics 11

**Objectives**: Determining the validity of a political, economic, legal or scientific argument calls for the weighing of evidence. Often this evidence consists of data. In this course, you will learn statistical methods for presenting and evaluating data. You will also develop ways of thinking critically about data collection and analysis.

**Textbook**: Intro Stats by De Veaux, Velleman and Bock (3rd Edition), Addison Wesley, 2009.

**Computer use**: You will need a calculator that can do basic arithmetic, including taking square roots. Use of a computer is only required to access information on the web site. The diskette included with your text contains useful discussion and examples, exercises, and data analysis instructions for Excel and Datadesk. We encourage you to use the diskette at home.
