| Abstract: | The Compass Plot, a new graphical methodthat combines the advantages of the star plot andthe analysis of means (ANOM), has beenintroducedfordisplaying the results of experiments. Incontrast to the star plot, this plot allows statistical inferences to be made for treatment and for factor effects. In contrast to ANOM, this plot is good for comparison in multiresponse experiments, a scenario becoming more commonplace in toxicology with the advent of increasing numbers of chemical mixture studies. An example of a 2 3 factorial chemical exposure experiment is considered here. |
