Course Content: Chapters 1-13.

Objective: Inferences, decisions, and predictions play a vital role in everyday life as well as in organized research. In many cases, a knowledge of statistics will allow a quantitative assessment of risk involved with each inference and hence improve inference-making abilities. Our goal will be to learn

• Basic techniques of solving elementary probability problems.

• Basic methods in descriptive and inferential statistics.

• To recognize how statistical methods may provide insight when solving problems in various academic disciplines.

• How to critically analyze the content of newspaper and magazine articles in quantitative and objective fashion.

• How to use statistical packages (Minitab and SAS).

Policies: You are responsible for all material in the assigned chapters whether it is discussed or not. You are also responsible for the material presented in class. It is your responsibility to attend class, be current with homework and take exams on time.

Attendance: I expect students to attend all classes, take notes and participate in class discussions. Attendance may be used in determining your final grade.

Homework: Homework is due by 3:30 pm on the assigned due date. Late homework will not be accepted. The lowest two homework scores will be dropped. All homework will be done neatly with work shown to receive full credit. Any grading issues should be submitted in writing within a week of the return date.

Testing: Students are expected to take tests on the announced dates. If a student is unable to take a test because of a legitimate reason, the student must make prior arrangements with me.

|Grades: Your final grade will be 15% homework, | | | |

|15% lab, 45% for three one - hour exams and 25% for the |90 – 100 |A | |

|comprehensive final. | | | |
