Factorial Split-Plot Designs for Hard-to-Change Factors (FSPD)

Real-world experimentation often includes factors that are easy-to-change and hard-to-change. Split-plot designs deal with these restrictions on randomization. This half-day “add-on” to the Experiment Design Made Easy workshop shows you how to set up these practical factorial designs and analyze the results. This is the workshop that resolves real-world randomization issues!


Prerequisite: Experiment Design Made Easy (EDME) workshop or current knowledge of using Design-Expert® software to set up factorial designs.

This class is only available as a private on-site workshop.

Factorial Split-Plot Designs for Hard-to-Change Factors (FSPD) (1/2 day)

Real-world experimentation often requires restrictions on randomization to make the experiment easier to run. Split-plot designs make this possible. This half-day “add-on” to the Experiment Design Made Easy workshop shows you how to set up these practical factorial designs and analyze the results, accounting for the differing variances in the hard-to-change (HTC) factors versus the easy-to-change (ETC) factors. As you will learn in this computer-intensive workshop, the split-plot structure also dramatically affects the power for detecting effects relative to a completely randomized design. Power for HTC factors is lower and for ETC factors higher. Delve into the pros and cons of using split-plot designs and gain proficiency in setting them up and capitalizing on the results. This is the workshop that resolves real-world randomization issues!

Course Outline

  Section 1: Regular Two-Level Split Plots
 
  • Introduction to split plots
  • Two-level factorial split plots
  • A typical case: 3 HTC factors and 2 ETC factors (gear distortion)
  • One extreme: 1 ETC factor (plasma treated paper)
  • The other extreme: 1 HTC factor, 4 arrangements (coating adhesion)
  Section 2: Multi-level and Optimal (Custom) Split Plots
 
  • Multi-level factorial split plots (paper tensile strength)
  • Optimal (custom) split plots (PCR DNA amplification and laminating hardwoods)
  • Conclusions

Prerequisites
