MATH 201 Applied Statistics

Fall 2013

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

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

Classroom: S. Halsey 202     Text: Introduction to the Practice of Statistics 7th edition, by David S. Moore and George P. McCabe.  Earlier editions of the text will likely be adequate, but you will have to allow for different page numbers and homework problem numbers.       Link to Day by Day notes

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.  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 410 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. Please attend class as often as you can.  You are responsible for any material you miss.  The Day By Day notes will help you greatly in this regard.

Text Box: Final Grades:
Grade	Points (Percent)
A	369 (90 %)
A-	357 (87 %)
B+	340 (83 %)
B	328 (80 %)
B-	316 (77 %)
C+	299 (73 %)
C	287 (70 %)
C-	275 (67 %)
D+	258 (63 %)
D	246 (60 %)
D-	234 (57 %)
F	233 or fewer

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, as 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 4). 2 – Sampling and Probability (November 6). 3 – Statistical Hypothesis Testing (December 11).

Homework:  I will collect several homework problems approximately once a week.  The due dates are listed on the course outline below.  While I will only be grading a few problems, I presume that you will be working on many more than just the ones 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 donÕt just put down a numerical answer; I want to see how you did the problem.  (You wonÕt get full credit for just numerical answers.)  The method you use and your description is much more important to me than the final numerical 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 percentage cannot be lower than your exam percentage.

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 2013 semester are Tuesday 10:30 to 11:30, Wednesday 3:00 to 4:00, 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 mathematics we will be exploring.  I do not feel that lecturing to you will teach you how to do mathematics.  I hope to be your guide while we learn some mathematics, but you will need to do the learning.  I expect each of you to come to class prepared to digest the dayÕs material.  That means you will benefit most by having read each section of the text and the Day By Day notes before class.

My idea of education is that one learns by doing.  I believe that you must be engaged in the learning process to learn well.  Therefore, I view my job as a teacher not as telling you the answers to the problems we will encounter, but rather pointing you in a direction that will allow you to see the solutions yourselves.  To accomplish that goal, I will find different interactive activities for us to work on.  Your job is to use me, your text, your friends, and any other resources to become adept at the material.
