COURSE DESCRIPTION: Methods of describing data: graphical methods, numerical summary
measures, exploratory data analysis. Probability, probability distributions, expected value.
Sampling distributions. Statistical inference: estimation and hypothesis testing for one-sample
and two-sample problems. Regression analysis. Demonstrating with standard statistical
software packages. Prerequisite: MATH-120 or equivalent.
TEXTBOOK: Introduction to the Practice of Statistics, 5th Ed., by Moore (adopted 8/06)
(Adopted 6/98: Introduction to the Practice of Statistics, 3rd Ed., by Moore)
(Adopted 8/93: 2nd Ed.; adopted 8/03: 4th)
COURSE OBJECTIVES: The course will enable students to:
1.
Demonstrate understanding of the basic principles of probability and statistics.
2.
Demonstrate understanding of the relationship between probability and statistics and the
importance of each in modeling practical problems.
3.
Use of descriptive statistical methods, both numerical and graphical, to organize and
summarize data.
4.
Apply the inferential statistical methods of estimation and hypothesis testing.
5.
Interpret the output of a statistical computing package.
6.
Write clear, complete, and logically correct presentations of the statistical analyses
performed in homework exercises and/or class projects.
In addition, graduate students shall be able to:
1.
Design, conduct, analyze and interpret their own statistical experiments in consultation
with the instructor and present their results in written reports.
2.
Demonstrate proficiency in the implementation of statistical procedures using a standard
statistical computer package.
