VIEW YOUR GRADES:

COUSE DESCRIPTION:

This course will cover data analysis including probability, distributions, sampling, hypothesis testing, confidence intervals, regression analysis, and nonparametric analysis.

PREREQUISITE:

A grade of C or better in Math 154A, Math 154AA, or equivalent; or a satisfactory score on Mathematics Assessment Test.

CALCULATOR:

A calculator with built-in one and two variable statistics functions is required for this class. The TI-30X IIS is one such calculator that is inexpensive.

TUTORING:

Tutoring is available at no cost in A201 (Math Success Center) on a drop-in basis.

STUDENT LEARNING

OUTCOMES:

1. Design and implement an unbiased study that will produce sound statistical results.

2. Generate and interpret statistics graphs from data that arise from surveys and experiments.

3. Implement the rules of probability.

4. Apply confidence intervals and test hypotheses to make conclusions about

data that come from practical applications.

5. Perform regression analysis to make informed predictions about relationships

between quantitative variables.

Your secret number is on your Quiz #1

EXAM POLICY:

Grading will be based on progress towards the final answer, and the demonstration of understanding of the concept that is being tested. The more you show me with steps and detail, the better your chances for partial credit.

MAKE-UP POLICY:

For Chapter Exams, and the Final, make-ups are not possible. In the case of a serious emergency, a chapter exam not taken will not be counted toward the final grade. However, it is essential to take the final exam at the scheduled time. During the first five minutes of each class, there will be a quiz that covers the main point from the previous lecture. Quizzes cannot be made up; however, the quiz with the lowest score will be dropped.

For Homework, you must show your work to get credit, half credit for completion and half credit for selected problems. Homework will be accepted late up to one week after it is assigned for half credit. You can turn in your homework early if you know you are going to miss the class. You can consult a classmate, a tutor, your instructor, or anyone for assistance on the homework.

COMMUNICATION

POLICY:

You can communicate with me either by coming to class or office hours, sending an e-mail. If you miss the class, it is your responsibility to pick up the class handouts or obtain the information either from your classmates or from me during the office hours.

I have students work together to help each other. Please feel free to ask me directly if you like to work with me one-on-one.

LEARNING

DISABILITIES:

If you have a certified learning disability, be sure to discuss your special needs with me during the first week of class. Learning disabilities will be accommodated.
