Chris Olsen
Chris Olsen taught mathematics at George Washington High School in Cedar Rapids, IA, for over 30 years. His teaching load typically included Advanced Placement* Statistics and Advanced Placement* calculus, precalculus, and an assortment of other classes. He is now teaching at Grinnell College in Grinnell, IA. He graduated from Iowa State University majoring in mathematics and philosophy, and in his graduate work concentrated on statistics, computer programming, and psychometrics and test development.
He has been involved nationally in workshops and conferences mostly relating to statistics for almost 20 years. He was the Iowa recipient of the Presidential Award for Excellence in Science and Mathematics Teaching in 1986, Regional Awardee of the IBM Computer Teacher of the Year award in 1988, and a recipient of the 1999 Siemens Award for Advanced Placement* in mathematics. He currently moderates the AP* Statistics Teacher Community website, and has reviewed materials for The Mathematics teacher, the AP* Central web site, The American Statistician, and the Journal of the American Statistical Association. He has also found time to author or co-author three books on statistics and its teaching.
He is a past member (twice) of the AP* Statistics Test Development Committee, and has been a table leader and question leader at the AP* Statistics reading for 12 years. Since the summer of 1996 has presented numerous workshops in AP* Statistics in the United States and internationally.
Course Description:
We will consider the four major content themes of AP* Statistics: exploratory data analysis, planning and executing statistical studies, probability and random variables, and statistical inference. We will stress the use of technology and during the course of the week. Our goal will be to expand your knowledge base with some in-depth discussions of the AP* Statistics topics to help with those tough questions your students are sure to ask. Generally, we will consider: the philosophy of the course, the statistical techniques needed, and communication as an essential part of "doing statistics." I will be bringing a large amount of AP* Statistics material (information, data, activities, tests & quizzes, bibliographies, PowerPoints, etc.).
The general sequence of statistical topics follows:
Day 1:
Our first day will be a plunge into the analysis of data. We will analyze data sets designed to highlight the important descriptive and inferential techniques, univariate and bivariate, in the AP* Statistics course. The data sets are long on interest, and can be taken right into the classroom.
Day 2:
Our second day will be a tour of Experimental Design (completely randomized design and randomized block design) and Sampling techniques (simple, stratified, cluster, systematic). We will focus on the decisions involved in choosing an experimental design strategy, methods of control of potentially confounding variables, and what factors would lead one to particular choices of an appropriate sampling design.
Day 3:
Our third day will begin with probability and random variables, and their role in statistical inference. From there we will explore the logic of statistical inference (hypothesis testing and confidence intervals). Then we will show how this logic threads its way through inferences about means, proportions, categorical data, and regression
Day 4:
On Day 4 we will continue our discussion of inference, and wrap up any remaining questions about the AP* Statistics course and its content. 
What to bring: Please bring the following items when you come:
• Your calculator (or better yet, a laptop)
• Favorite scribbles or activities to share (preferably electronically)
• Lots of questions about content and teaching strategies
• A cheerful smile
