Mark Anderson and Pat Whitcomb (2000), DOE Simplified, Productivity Inc., Chapter 2.One-Factor Tutorial 1Welcome to Stat-Ease’s introduction to analysis of variance (ANOVA). The objective of this PowerPoint presentation and the associated software tutorial is two-fold. One, to introduce you to the Design-Expert software before you attend a computer-intensive workshop, and two, to review the basic concepts of ANOVA. These concepts are presented in their simplest form, a one-factor comparison. This form of design of experiment (DOE) can compare two levels of a single factor, e.g. two or more vendors. Or perhaps to compare the current process versus a proposed new process. Analysis of variance is based on F-testing and is typically followed up with pairwise t-testing.Turn the page to get started!If you have any questions about these materials, please e-mail StatHelp@StatEase.com or call 612-378-9449 and ask for statistical support.1General One-Factor Tutorial(Tutorial Part 1 – The Basics)Instructions:1.
