Abstract : This paper is an attempt to understand, measure and compare dispersion effects at different levels of factors in factorial experiments. The simplest setting is considered in order to develop better comprehension and insight. The properties of the proposed descriptive measures are examined. A method of adjusting residuals and its use in comparing dispersion effects are discussed. Illustrative examples are also given. The problem considered in this paper arises in quality control studies and the methodologies are applicable to industrial experiments. (Author)
