Course Description:

 

An introductory noncalculus statistics course.  Topics include descriptive analysis and treatment of data, probability, statistical inference, linear regression and correlation.

 

 

 

Core Learning Outcomes:

 

Upon completion of this course students will

1. Describe, analyze and display statistical distributions.

2. Display, analyze and interpret bi-variate data

3. Use appropriate techniques to make valid statistical     inferences.           

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 Instructional Methods:

 

  1. Blackboard Web site
  2. Blackboard Discussion Group
  3. Textbook Web Site Tutoring Videos
  4. Addison-Wesley tutoring support by phone
  5. Weekly Homework Assignments
  6. Blackboard Practice Tests
  7. Four online tests
  8. Proctored on-campus midterm and final exam

 

 

 How is this course organized:

 

This is not a self paced course.  Two proctored exams have deadlines and Weekly Assignments are due twice a week in summer.

 

Text(s) and Course Materials:

 

Essential Statistics, 4th ed. Mario F Triola bundled with MyStatLab access key. Required textbook.

A TI-83/TI-84Plus graphing calculator is required. Proctored testing will be significantly easier with the TI-84.

 

 

Progress Report:

 

By the end of the 3rd week of the semester, you will have an opportunity to evaluate your progress in this course and decide if you need to make any adjustments (additional study, tutoring, conference with instructor) to assure your success in this course.
