MATH 201 Applied Statistics

Fall 2009

Section 001 8:00 to 9:00 M W F

Section 002 9:10 to 10:10 M W F

Instructor: Dr. Chris Edwards      Phone: 424-1358 or 948-3969     Office: Swart 123

Classroom: Swart 2   Text: Introduction to the Practice of Statistics 6th edition, by David S. Moore and George P. McCabe

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:  An introduction to applied statistics using a statistical computing package such as MINITAB.  Topics include: Descriptive statistics, elementary probability, discrete and continuous distributions, interval and point estimation, hypothesis testing, regression and correlation.  Credit cannot be earned for both PBIS 189 and Mathematics 201.  Prerequisite: Mathematics 104 or 108 with a grade of C or better.

Course Objectives: (Click here for full document.)  The goal of statistics is to gain understanding from data.  This course focuses on critical thinking and active learning.  Students will be engaged in statistical problem solving and will develop intuition concerning data analysis, including the use of appropriate technology.

Specifically students will develop

•     an interest and aptitude in applying statistics to other areas of human inquiry

•     an awareness of the nature and value of statistics

•     a sound, critical approach to interpreting statistics, including possible misuses

•     facility with statistical calculations and evaluations, using appropriate technology

•     effective written and oral communication skills

Grading: Final grades are based on 500 points:

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 three 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 - Displays and Regression (October 7).  2 - Sampling and Probability (November 11).  3 - Statistical Hypothesis Testing (December 16).

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.  To aid in your study groups, I will be distributing a class roll of both sections I am teaching this semester.

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 2009 semester are 10:20 to 11:00, Monday, Wednesday, and Friday, and 2:00 to 2:50 Tuesday, 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.  Keep in mind that the goal is to learn statistics, not to pass the exams.  (Incidentally, if you have truly learned the material, the exam results will take care of themselves.)
