Introduction

Abstract

This book presents graphical tools for the design and analysis of statistical experiments. It has practical significance for engineers factory and service workers and managers scientists and technicians involved in planning and analyzing experiments and experimental data. It shows how each step in planning and analyzing an experiment can be aided by the use of graphical methods. For the actual experimental layouts factorial designs are emphasized because their structure permits graphical representations for designs with as many as ten factors. Mixture designs and nested designs are also considered. Unlike most texts on the design of experiments the analysis of experimental data does not dominate the discussion here but it is included as supporting material since graphical tools for design and the statistical models for analysis are interconnected.
