I. Purpose

**Catalog Description: **Offered
first and second semesters. Offered as demand warrants in the summer session.
Check with advisor regarding department designation and transfer information.
Three hours lecture and discussion a week. Fee: $10.00.

Organization and analysis
of data, frequency distribution, average, measures of variability, probability,
normal distribution, sampling, estimation, hypothesis, quality testing control,
significance levels, t test, z test, Ç^{2} test, regression
and correlation index numbers. This course includes the use of computers to
analyze statistical data. Prior experience with computers is not necessary.
Prerequisite: Mathematics 101 or Math 93 (Intermediate Algebra) or equivalent.
3 semester hours.

**Course Objectives: **A
course designed to enable the student to develop sufficient skills in probability
and statistics to satisfy the student's needs in a variety of majors. The emphasis
is on applications of statistics to real world problems that the student may
encounter in his/her major, career or life.

1. To learn the vocabulary pertinent to a first course in elementary statistics.

2. To develop a basis for understanding and applying the concepts, principles and skills of statistical analysis.

3. Study of probability of events and application to real problems.

4. To develop a basis for reading, interpreting and evaluating statistical research in student's field of interest.

5. To develop a foundation for further study.

6. To develop a basis for questioning the validity of conclusions derived from statistical studies.

7. To use problem solving techniques in the development of statistical formulas for confidence intervals and hypothesis tests.

II. Course Policies

**A. Attendance:** Students
are recommended to attend classes regularly because exams will be based on the
material presented in class as well as assigned readings. In addition, homework
problems will be collected every class period, and late homework will not be
accepted. Students should strive to arrive in the room(s) before class begins.

**B. Class Participation:
**Participation is not required, but it is strongly recommended.

**C. Grading:** Grades
will be based upon the student's performance on four or five exams valued at
100 points each, homework assignments worth a total of 100 points, and three
statistical projects worth a total of 75 points (guidelines for these projects
will be distributed later). The grading scale is as follows: 90-100%= A, 80-89%
= B, 70-79% = C, 60-69% = D, and 0-59% = F.

**D. Extra Credit:**
At least one extra credit project worth 10 points will be offered..

**E. Tutoring, extra help
sessions: **Contact the instructor or the Instructional Assistance Center.
I generally will be available 10-20 minutes before the class begins for consultation.
If a student needs additional help, please contact me about scheduling another
time.

**F. Make-up Test Policy:**
If a student is unable to take an exam at its regularly scheduled time, he or
she will be given a make-up exam only if he or she contacts me before the regularly
scheduled exam. For athletes and club members who are on the road at times,
a written request from the coach or faculty advisor is required in advance.
Make-up exams will be given during the final week of class (and, needless to
say, the make-up exam will be different from the regular exam).

**G. Assignment Format
and Deadlines: **Instructions and deadlines will be announced in class and
distributed to the class.

**H. Plagiarism and Cheating:**
Cheating and plagiarism will be punished severely. Please consult with the *Student
Handbook* regarding College guidelines.
