Offering a planned approach for determining cause and effect, this work provides researchers with the statistical means to analyze how numerous variables interact. With this second edition of DOE Simplified, Mark Anderson and Patrick Whitcomb retain their lively approach to the learning of fundamentals. They lighten up the inherently dry complexities with interesting sidebars and amusing anecdotes. In this edition, they add new and updated information, including a four-step planning process for designing and executing experiments with a consideration of statistical power. Accompanying this book is a 180-day trial for the new version of Stat-Ease's software: Design-Ease(R), v. 7. This educational program assists with mathematic computations, so as to allow one to focus on analysis of the data.
