Instead of using a factorial design for studying water sorption characteristics and its assumption of homogeneity of variances among cells, a multivariate statistical analysis approach is presented. This considers interactions and heterogeneous variances and leads to simultaneous comparisons of all aw levels. By applying this approach to a study of the water sorption characteristics of Argentine sorghum, significant differences were obtained between hybrids with the conclusion that they should not be mixed in storage. Confidence intervals were presented which will be of use both in predicting storage behavior and in comparing results from different researchers.
