How to Save Runs with Fractional Factorial Designs

How to Save Runs with Fractional Factorial DOE's

Learn how to gain experimental efficiency by using fractional factorial designs when many factors are involved. Fun case studies are used to reinforce the analysis techniques you learned in the "Finding the Vital Settings via Factorial Analysis" course. By the end of the course you will know:

  • How and when to use fractional factorial designs.
  • How to choose the fractional factorial design that will meet your objectives.
  • What is aliasing and how does it affect your results.
  • Interpreting graphs to optimize your product or process.

Expected completion time: 2 hours

Prerequisite: Understanding of factorial designs using Design-Expert software
