Text: The Basic Practice of Statistics 4th edition, by David S. Moore.
Required Calculator: TI-83, TI-83 Plus, or TI-84 Plus, by Texas Instruments. Other TI graphics
calculators (like the TI-86) do not have the same statistics routines we will be using and will cause you
troubles.
Catalog Description: Descriptive statistics/elementary probability/basic problems of statistical
inference: estimation, confidence intervals, hypothesis testing, regression and correlation. Prerequisite:
Mathematics 100 with a C or better or placement.
Course Objectives: This course focuses on critical thinking and active learning. Students will be
engaged in problem solving and will come to understand that a "problem" is a situation that is unfamiliar
and one for which a solution is not immediately evident. Being stuck is a natural state of problem
solving and an essential part of improving thinking.
Specifically students will
• collect data, observe patterns, make and verify conjectures
• improve their ability to reason logically
• develop effective written and oral communication skills
• improve skills related to critical thinking, problem solving and creativity
• use and understand symbol systems and quantitative methods
• understand principles of mathematics and the sciences.

Attendance is a very important component of success in my class because many of the skills and lessons
we will learn will be a direct result of classroom activities that cannot be reproduced easily. Thus, final
grades are based on attendance as well as total points earned. The number of quiz scores that may be
dropped is based on absences.
Presentations: There will be four presentations, each worth 20 points. The descriptions of the
presentations are in the Day By Day Notes. I will assign you to your groups for these presentations
randomly, but I want to avoid you having the same members each time. I expect each person in a group
to contribute to the work; you can allocate the work in any way you like. If a group member is not
contributing, see me as soon as possible so I can make a decision about what to do. Part of your
presentation grade will be based on your own evaluations of how

each person contributed to the presentation. The topics are: 1 Dropped
Displays (September 27). 2 – Regression (October 18). 3 - Sampling Absences
Quizzes
(November 15). 4 - Statistical Hypothesis Testing (December 13).
Quizzes: Approximately once a week, we will have a quiz on the
current material. These quizzes are a way for me to provide feedback
to you on your progress in the course. You will be allowed to drop
up to 2 quizzes, based on your course attendance.
Homework: I will collect three homework problems approximately
once a week. The due dates are listed on the course outline below.
While I will only be grading three problems, I presume that you will
be working on many more than just the three I assign. I suggest that
you work together in small groups on the homework for this class.
What I expect is a well thought out, complete discussion of the
problem. Please don't just put down a numerical answer; I want to
see how you did the problem. (You won't get full credit for just
numerical answers.) The method you use is much more important to
me than the final answer. Important Grading Feature: If your
homework percentage is lower than your exam percentage, I will
replace your homework percentage with your exam percentage.
Therefore, your homework grade cannot be lower than your exam
grade.
Office Hours: Office hours are times when I will be in my office to
help you. There are many other times when I am in my office. If I
am in and not busy, I will be happy to help. My office hours for Fall
2011 semester are 10:20 to 11:00, Monday, Wednesday, and Friday,
and 3:00 to 4:00 Thursday, or by appointment.

Philosophy: I strongly believe that you, the student, are the only person who can make yourself learn.
Therefore, whenever it is appropriate, I expect you to discover the statistics we will be exploring. I do
not feel that lecturing to you will teach you how to do statistics. I hope to be your guide while we learn
some statistics, but you will need to do the learning. The textbook we will be using for this class will
require you to actually read it to master the material.
My idea of education is not "Teaching is telling and learning is listening". I believe that you must be
active in the learning process to learn well. My job as a teacher, therefore, is not to tell you the answers
to the problems we will encounter; rather it is to point you in a direction that will allow you to see the
solutions yourselves. To accomplish that goal, I will work to find different interactive activities for us to
work on. Your job is to use me, to use your text, to use your friends, and any other resources.
