PBIS 189 Introduction to Statistics

Spring 2007

Section 004 1:50 to 2:50 M W F

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

Classroom: N. Halsey 237    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:  (Click here for full document.)  This course focuses on critical thinking and active learning.  Students will be engaged in problem solving and will come to understand that a ěproblemî 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

     ď collect data, observe patterns, make and verify conjectures

     ď improve their ability to reason logically

     ď develop effective written and oral communication skills

     ď improve skills related to critical thinking, problem solving and creativity

     ď use and understand symbol systems and quantitative methods

     ď 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.  Minimum scores for each grade and attendance level are as follows:

Presentations:  There will be four presentations, each worth 20 points.  The descriptions of the presentations are on the Days189Spring2007-004 file.  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.  The topics are:  1 - Displays (February 16).  2 – Regression (March 9).  3 - Sampling (April 11).  4 - Statistical Hypothesis Testing (May 9).

Homework:  I will collect 3 homework problems approximately once a week.  The due dates are listed on the course outline below.  While I will only be grading 3 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 Spring 2007 semester are 10:20 to 11:00, Monday, Wednesday, and Friday, and 1:50 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 teaching / learning 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.)
