Statistics 160: Statistics and Data Analysis, Syllabus
Spring 2009

Welcome to Stat 160. This is a first course in Statistics. Much of this course is on the Web. Students should look at the Web page frequently. Before each class, the student should bring up that day's lecture and read through it.

It is the world-wide-web so you may have a computer at home from which you can reach the web. Also, you can use any of the computers in the university's labs to get to the web. The Bernhard center is convenient and has a good many computers. Use any web browser (Netscape, Mozilla, Internet Explorer, ...) and go to the following location:

The main purpose of Stat 160 is to show the student how useful statistics is in their world. This course will give the students a basic understanding of statistics, which will enable them to see how statistics can help them to make better decisions as consumers, students, parents or professionals. The method of resampling will be used throughout the course. This will allow us to avoid the use of any higher math than the level of Math 110 which is the prerequisite level for Stat 160. Resampling will also allow us to look at some interesting probability problems without math anxiety. Students will learn basic descriptive statistical and graphical procedures for analyzing data sets. Some simple inferential procedures, parametric and nonparametric, will also be taught based on resampling. Students will use these procedures in the daily group activities. Many of these daily activities will use real data sets. One main goal of these activities will be to answer predetermined questions as well as to explore the data to formulate further ideas and questions about the variables defined in the study and their underlying relationships.

This course has the prerequisite of Math 110 which is essentially high school algebra. It will not make use of any higher math and it will not be formula driven. You do not need prior knowledge of computer analysis.

Pin Number

For this course, each student pays a course fee of $35 upon registering. During the first class meeting a registered student will obtain an unique pin number from his/her instructor. This number is extremely important. It allows each student to take the pre and post quizzes as well as the exams. So please record it in a safe area. Along with a pin number the student will receive his user name. This may or may not be the student's last name. The instructor keeps a list of pin numbers and user names, so if a student forgets his/her number he/she should contact his/her instructor. On the Final Exam, the student must use his/her username.

The fee paid by the student goes to the Department of Statistics which in turn pays the Statistical Computation Lab (SCL, 3379 Rood Hall) for the services that it provides for this course. These services include but are not limited to: the maintenance of the on line web server for this course; the production of the course's web page; the preparation and updating of the online text book; the production of the online statistical software; the preparation of and the record keeping of the pre and post quizzes; the record keeping of the grade book; and the preparation of and record keeping of the group activities. Some of these services are discussed next. The electronic text book is the only text book for the course. It is a book, (table of contents, chapters, index, etc.). A textbook for this course would run about $110.00. So the staff of 160 has already saved you $75.00!

For Help in This Class

Students should feel free to see the instructors during their office hours or to make appointments if need be at more convenient times. There are five sections of this course and the same schedule is used in all of these sections. So if time conflicts prevent you from visiting your instructor, please visit another instructor during his/her office hours. Please feel free, also, to contact Dr. McKean (director of Stat 160) for an appointment.

e-mail is a handy tool for answering class questions. So please feel free to use e-mail to ask the instructors questions on the material and/or the class.

The student is advised to go to the web page and click on the services described next.

Text Book

The text book for this class is online. There are two ways to access it.

At the main home page, click on Schedule and then on the current date. This brings up the list of sections which will be covered in class that day. Clicking on a section, pulls up that section of the text. Students are encouraged to:
Read these sections.
Download these sections.
Take the prequiz. After reading the sections, you should be prepared for it.
Bring the downloaded sections to class and take notes on them.
Full Copy:
There is a full copy of the text under Book on the web page. This version is the same as the daily version except that it also includes an index.
The preparation of the text is a service supplied by the Statistical Computation Lab (SCL).


For most lectures, students must take a pre-quiz. On the home page, just click on Quiz and then Pre-Quiz. The due date and time are given for each quiz. It is usually due by 9:30AM the day of the lecture. This quiz is over the material that will be discussed in class that day. The pre-quiz usually consists of 4 questions (multiple choice) which can easily be answered once the material is read. To take the quiz, students:

Students fill in the information (user name and pin number). Your name and your pin number are very important. If you enter the wrong pin number, your quiz will not be correctly recorded.
Answer the questions.
Click on Submit.
Only click on submit after all questions have been answered.
We would suggest downloading a copy of the quiz. These make great study aids for the Mid-Term and the Final.

The maintenance and record keeping of these quizzes is a service of the SCL.


There will be a post-quiz after every two lectures.. On the home page, just click on Quiz and then Post-Quiz. The due date and time are given for each quiz. This quiz usually consists of 5 multiple choice questions over the material covered that week. Students take the post-quiz the same way as a pre-quiz.

The maintenance and record keeping of these quizzes is a service of the SCL.


Students must complete a web survey which will provide some of the data to be used during the semester. The due date for the completion of the survey will be announced in class. Successful completion will count as a 4 on the first prequiz. Failure to complete the survey by the due date will result in a ZERO score on the first pre-quiz.

The survey is a service of the SCL.

Questions and Answers

There is a question & answer section on the home page of the course. If you have an interesting question, please e-mail it to your instructor. If it has educational value in regards to Stat 160, an answer will appear.

Group Activities

For a typical class, we begin with a discussion (lecture) for about the first 30 minutes. This is followed by a Group Activity. These pertain to the lectures for that day and, besides counting towards a student's grade, are an important way to keep up with the material. Usually students work in pairs for these activities. At the end of class the group activity must be turned in.

Calendar There is a calendar on the quiz page which has the quizzes and group activities by date.

The maintenance and record keeping of these group activities is a service of the SCL.

Crib Sheets:

To avoid memorization of formulas, crib sheets will be allowed. For the midterm, a sheet of paper (8.5 x 11) can be used (both sides). Two sheets are allowed for the final.
