Course Description

Emphasis is on understanding statistical methods. The major topics include descriptive statistics, measure of location and dispersion, sampling and sampling distribution, correlation and regression, confidence interval, hypothesis testing, test of independence, and analysis of variance.  The use of the graphing/statistical calculator the TI-83 is also a focus of the course.  

Tools: TI 83/TI 83 Plus or TI 84 Plus Calculator is required (The TI 83 has specific statistical functions not found on other graphing calculators). You are expected to bring the calculator to each class. We will go over the how to use the calculator in class, however, as the course is quite fast paced our time is limited, you will need to use the calculator on your own in order to be successful in this course. You are more than welcome to come to my office or math lab hours for additional help.

Objectives:

• Statistically describe sets of data.

• Apply basic laws of probability.

• Formulate a probability distribution.

• Formulate and test hypotheses testing of one, two, and more than two populations.

• Formulate and analyze point and interval estimates for parameters.

• Find the correlation between two variables and the linear regression equation describing the relation between the two variables.

 Entry Level Skills: Skills you need to have known prior to enrollment in this course

• Solve linear and non-linear equations.

• Simplify advanced numerical expressions (order of operations).

• Plot and interpret points on Cartesian coordinate system.

• Plot linear equations using slope-intercept method.

• Translate verbally stated problems into appropriate mathematical forms.
