Abstract : There are three primary reasons to transform data: lack of symmetry, nonconstant variance, and interaction between factors. We present a display that has separate graphics designed to diagnose each of these conditions. The user is thus free to weigh the importance of each of these three criteria for the problem at hand, and then to choose the transformation that seems most suitable. As is the practice of many data analysts, this system uses only a few select transformations rather than transformations to arbitrary powers. Although this system is demonstrated with data from designed experiments, it may also be used for regression problems.
