Ran in 4 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 an elementary course. Material includes regression analysis for linear and nonlinear models, analysis of variance, statistical inference, single and multiple comparisons, and an introduction to the design of experiments including single factor designs, multifactor designs, response surface methods, d-optimality (with empirical and mechanistic models), and the analysis of undesigned data. Applications to process improvement, product development, and research problems will be explored. Use of statistical analysis software to apply these techniques.

  • It's an easy course for Engineering curriculum but do not underestimated it. As long as you attend all lectures & do practices you don’t need to spend > 1 hr per week for this course (outside assignment). Midterm & Final are very fair and Professor Lena is very considerate when making them. Some questions on the exam she just directly taken from exam review session, Attend them!

  • Assignments and exams are in take-home format. The content of the class is very theoretical, but the assignments require you to be proficient in a statistical tool, I initially chose excel, but later found that R was simpler, and I ended up using the dumb software Minitab to check my assignments

  • Not a super easy course but completely reasonable
