Design of Experiments

Course ID DOX
Format Classroom

Learn the scientific method for designing and conducting effective experiments. You’ll identify the variables that have the greatest impact on product-level quality and use graphical techniques to analyze data.

Success is no accident with design of experiments (DOE). A strategically planned and executed experiment gives you a great deal of information about the effect on a response variable due to one or more factors. You'll get the basics of DOE from this course – scientific method, steps for designing and conducting effective experiments, and statistical and graphical tests for significance. You'll also learn to set up, conduct, and analyze two-level factorial designed experiments. After this course, you'll be able to identify what factors impact quality and what you can do to improve.

Course Overview

Learning Objectives:

  • Build a model and check that model.
  • Apply the foundation skills necessary to move on to more complex, multilevel designs.
  • Understand experimental analysis: main and interactive effects, experimental error, normal probability plots, identification of “active” efforts, and residual analysis.
  • Identify the variables that have the greatest impact on product-level quality.
  • Understand experimental design essentials, be able to plan an experiment (choose factors, levels, design matrices), and set up, conduct, and analyze a two-level factorial experiment.
  • Apply the fundamentals of designed experiments, including comparative experiments, process optimization, and multiple variable designs to continuously improve all product stages.
  • Know how to use simple graphical techniques to analyze data.


Participants should be able to work with high-school level algebraic formulas. Please note no special software is needed.
