This is a work in progress. It will be completed by the end of the day on 04 January 2016.

Learning outcomes

  • Learn the basic terminology of experiments: responses, factors, outcomes, real-world units vs coded units, confounding
  • Analyze and interpret data from an experiment with 2, 3 or more factors by hand
  • Use R to do the analysis, and interpret the various plots, such as the Pareto plot
  • Analyze and interpret data from an experiment with 3 or more factors
  • Recognize when to use a fractional factorial, to go mostly the same results as from a full factorial
  • Understand when to use screening experiments
  • Use the concepts of response surface methods to systematically reach an optimum
  • What you can do when you make a mistake, or hit against constraints.

Extended readings/practice
