The third edition of DOE Simplified: Practical Tools for Effective Experimentation is now available. This comprehensive introductory text is geared towards readers with a minimal statistical background. In it, the authors take a fresh and lively approach to learning the fundamentals of experiment design and analysis. This edition includes a major revision of the software that accompanies the book (via trial download) and sets the stage for introducing experiment designs where the randomization of one or more hard-to-change factors can be restricted. It also includes a new chapter on split plots and adds coverage of a number of recent developments in the design and analysis of experiments.
P.S. There are still some copies of DOE Simplified, 2nd Edition available on clearance if you would like to learn the fundamentals of DOE while saving money.
