Ran in 5 of the last 7 terms. Winter 2027: not on the schedule. Spring 2027: schedule not out yet.
A course in practical statistics at a level one step beyond a typical introductory course. Material includes regression analysis for linear and nonlinear models, analysis of variance, statistical inference, single and multiple comparisons, blocking (variance reduction techniques) and design of experiments including single factor designs, multifactor designs, fractional factorials and screening designs, and an introduction to response surface methods. Applications to process improvement, product development, and research problems will be explored. Use of statistical analysis software to apply these techniques throughout the course.

Very very very very very boring stats course. Go to lectures and pay some amount of attention and it'll be quite simple, if taken with Dr. Ahmadi.
