This course surveys descriptive and inferential statistics with emphasis on practical applications of statistical analysis. The principles of collecting, analyzing, and interpreting data are covered in this course. It examines the role of statistical analysis, terminology, the appropriate use of techniques, and interpretation of statistical findings through the applications and functions of statistical methods.
This graduate-level course is 6 weeks. This course is available to take individually or as part of a degree or certificate program. To enroll, speak with an Enrollment Advisor.
Introduction to Statistics

Distribution and Variation
- Determine whether or not data is normally distributed.
- Utilize graphical representation to display data.
- Differentiate among the various levels of measurement.
- Calculate range, variance, and standard deviation for grouped and ungrouped data.
- Interpret the significance of standard deviation using the Empirical Rule.
Introduction to Inferential Statistics and Test of Hypothesis
- State the five steps in the decision rule.
