Analysis of Means--A Graphical Procedure

Summary: The methods of analysis described in this article are an extension of Shewhart control chart techniques. They tend to encourage the design of experiments and are an effective method of presenting the findings. They involve dealing directly with means in contrast to the analysis of variance, in which means are compared by taking ratios of mean squares. The underlying concepts of these two procedures are basically the same; the conclusions are usually the same, but the nature of some differences are indicated in this article. Additional benefits of the analysis of means are outlined in the summary.
