Experiment Design Made Easy


Tricks of the Trade for the Experienced Statistical Experimenter

Learn the tricks of the trade for design of experiments (DOE) in this 2-day computer-intensive workshop. In real life your DOE data may be messy unlike the storybook data cases you normally find in textbooks and classes. In this course, we'll teach you how to get the most out of a difficult design. We'll illustrate the effects that outliers, botched runs and missing data can have on your analysis. The focus will be on two-level factorials—the most widely used tool for breakthrough improvements in products or processes. Real-Life DOE is not offered as a public class.

A Case-Driven Format for a Real Feel
In the Real-Life DOE workshop you will take on the role of detective to solve tough cases.

Gain hands-on experience with DOE simulations and case studies. Experiment with:
  • "Improving extruder operations" (food processing)
  • "Blow room performance" (textiles)
  • "The translucent ceramic" (material science)

  • Apprehend the devious outliers that kill your DOE. Study:
  • "A case to test your metal" (aluminum castings)
  • "Two too many outliers" (tooling)
  • "The not so obvious problem" (coatings)

  • Diagnose residuals and salvage your data. Study:
  • "Pits in pies" (food processing)
  • "The case of the loose collet" (lathe cutting)

  • Analyze multilevel factorial designs. Look at:
    ·"Soda-bottle filling" (beverage)
    ·D-optimal factorial designs·Split-plot analysis (paper pulp)
