Course Description: Statistics I is a course intended to give the non-mathematics major an introduction to the fundamental concepts and methods of statistics. The course consists of an introduction to descriptive statistics and statistical inference. Topical coverage includes basic measures of central tendency and variability, elementary probability theory, normal distributions, the student t-distribution, confidence intervals and hypothesis testing. The TI-83 graphing calculator is required for the course.

Course Objective: The primary objective for this course will be the development of independent learning skills. The growth of critical thinking and mathematical problem solving abilities will be accomplished principally through a student-centered learning process. This process will necessarily entail study and thought outside the classroom, in addition to independent work during class. Through this process, students will develop the crucial ability to learn on their own.

Attendance & Punctuality: In order to effectively accomplish the main course objective, students are expected to attend every class and to be on time. If you are absent from class for any reason, it is your responsibility to find out what you missed, including any announcements. You may find out what you missed from your classmates or by contacting me directly. Excessive absence or lateness may result in a lower final grade for the course.

Textbook: Peck, R., Olsen, C., and Devore, J., Introduction to Statistics and Data Analysis, 2nd edition, Brooks/Cole, 2005, along with the accompanying TI-83 Graphing Calculator Manual.

Academic Honesty: All forms of academic dishonesty will not be tolerated. First-time offenders will be issued an immediate grade of F for the course and a permanent record of the cheating offense will be included in your academic transcript.

Miscellaneous: In order to avoid disruption during class, all cell phone, beepers, and the like are to be turned off before entering the classroom.

Grading Policy: Final grades will be determined as follows:
Quizzes (6) 300 pts.
Tests (2) 400 pts.
Final Exam 300 pts.
Participation 100 pts.
Total 1100 pts.
Notes: (1) All students must be present for all tests and quizzes. No make-ups will be given
and a grade of zero will be assigned for any missed test or quiz.
(2) The lowest quiz grade for each student will be dropped at the end of the semester.
(3) Any student who accumulates 650 points on quizzes and tests before the final
exam (after the lowest quiz grade has been dropped and not counting the participation
grade) and who continues to attend class until the end of the semester will be
exempted from the final exam and receive an A for the course.
(4) The final letter grade assigned to each student will be determined based on
performance in the above listed categories relative to the other students in the course.
