Sample Course Homepage: Recent Semester

Usually Offered: Fall, Spring, and Summer I Semesters

Learning Outcomes: By the end of the term successful students should be able to do the following:

  • Understand and be able to correctly use basic statistical terminology.
  • Recognize and evaluate variation in data using basic parameter estimation and hypothesis testing.
  • Compare data sets using parameter estimation, hypothesis testing and analysis of variance.
  • Recognize and evaluate relationships between two variables using simple linear regression.
  • Apply basic 2K design of experiments in order to study and improve engineering processes.
  • Understand and be able to apply simple principles of probability, parameter estimation, hypothesis testing, analysis of variance, simple linear regression, and design of experiments to engineering applications.
