2. Organize and summarize data, and represent graphically the important information contained in a data set.
3. Compute numerical quantities that measure the central tendency and dispersion of a set of data.
4. Understand the basic properties of probability.
5. Determine probabilities using postulates, rules of probability and various probability distribution tables.
6. Distinguish between discrete and continuous variables.
7. Compute the mean and standard deviation of a probability distribution.

## Course Time Commitment and Expectations

For every credit hour, students should plan to spend an average of 2-3 hours per week for course-related activities in a 15-week course. For example, a 3 credit hour course would average an average 6-9 hours per week to read/listen to the online content, participate in discussion forums, complete assignments, and study the course material. For 10  and 6-week courses, the amount of time per week will be higher so all course competencies, module outcomes, and assignments will be covered.

Aside from typical reading assignments, this course has the following (Please Note: This list is subject to change based on the discretion of the instructor facilitating this course.):

Assignment Points %
Discussions – Individual (5 @ 15 points each) 75 7.5%
Discussions – Small Group (5 @ 10 points each) 50 5%
Practice Problems (5 @ 10 points each) 50 5%
Application Problems (5 @ 25 points each) 125 12.5%
Practical Project Portfolio Contributions (5 @ 20 points each) 100 10%
Quizzes (5 @ 40 points each) 200 20%
Tests (5 @ 100 points each)* 400* 40%
TOTAL 1000 100%
* Five tests are taken but the lowest score is dropped.
