Course Description

This course is designed to introduce students to the techniques of statistical description and inference. Coverage will include the study of data distributions, descriptive measures, probability theory including standard probability distributions such as the normal and binomial; sampling distributions, the basic statistical inference methods, and applied linear regression techniques. Additionally, students will be introduced to the use of spreadsheet software to perform basic data analysis.

Upon completion of this course, students should be able to perform basic data analysis with the use of a calculator and tables along with performing the same analysis with the use of spreadsheet software.

Policies and Requirements

Problems
The only way you can really understand probability and statistics is by doing many problems. It is important to realize that this course is different than many others in the following respect: you may understand both the lectures and the book quite well, but not be able to do problems efficiently. The list of problems suggested in the syllabus is currently tentative.

Homeworks
A large number of problems from each chapter are suggested for practice. Your proficiency in this course will improve if these problems are done faithfully and in a timely fashion. A portion of these problems will be assigned as homework and graded. No late homework will be accepted. Solutions to problems will be posted on the course web page.

Exams
Exams will test both technical ability to carry out standard procedures and your understanding of important concepts. Do not expect exams to consist of homework assignments. Quizzes and exams are closed book. You are required to take all tests. Only under exceptional circumstances, when legitimate and verifiable reasons are provided, makeup tests will be given.

Etiquette
Classroom etiquette requires that you come to class on time and remain until the assigned time for the class to end. Please do not leave early unless it is absolutely necessary. You are expected to attend the section in which you are enrolled. Permission is required to attend any section other than the one in which you are officially enrolled. Attendance will be taken and will be accounted partly for class participation portion of your final grade.

Help Sessions
will be help sessions for the course conducted by FuShiang Tseng (Sean). Sean will discuss homework and other problems during the help sessions. Seanís email tsengf@mgmt.purdue.edu. Schedule: MW 6:00-7:00pm in Krannert G5 starting January 14, 2002.
