A calculus-based survey of topics in probability and statistics emphasizing applications.

MAT 321 meets for three hours of lecture per week.

MAT 193 and MAT 271 with grade C or better.

After completing MAT 321 the student should be able to

- understand the relationship between a question that arises in the natural, computer, economic, and social sciences and the nature of the numerical data that are needed in order to provide an answer to the question
- formulate the question in a mathematical context, set up the required mathematical procedure and carry out the required mathematical analysis and calculations, with appropriate use of a calculator, to answer the questions.
- understand why some statistical procedures are better than others in certain contexts.

Students should be able to demonstrate through written assignments, tests, and/or oral presentations, that they have achieved the objectives of MAT 321.

Evaluations are based on homework, class participation, short tests scheduled examinations covering students' understanding of topics that are covered in MAT 321. Most instructors give "closed-book" in-class examinations with no books, notes, "crib sheets", etc. allowed. However they encourage students to use the most advanced calculators available in both homework assignments and examinations. Statistical tables and a few of the more complex formulas are provided for use on exams at the instructors' discretion

Students' grades are based on homework, class participation, short tests, and scheduled examinations covering students' understanding of the topics covered in MAT 321. The instructor determines the relative weights of these factors.

Attendance policy is set by the instructor.

Due dates and policy regarding make-up work are set by the instructor.

The instructor sets all test dates except the date of the final exam. The final exam is given at the date and time announced in the Schedule of Classes.

The mathematics department does not tolerate cheating. Students who have questions or concerns about academic integrity should ask their professors or the counselors in the Student Development Office, or refer to the University Catalog for more information. (Look in the index under "academic integrity".)
