Classical interaction plots can be difficult to interpret, especially when there are more than two levels per categorical factor. Analysis of Means (ANOM) and the ANOM slice chart together can enable one to easily interpret effects in the presence of an interaction. The analysis of means (ANOM) is a multiple comparisons graphical procedure developed by Ellis Ott. The key idea is that ANOM uses a decision chart to compare means, rates, proportions, and variances. The chart makes it easy to assess both statistical and practical significance and may be used with one-way & two-way studies. The ANOM slice chart is an extension of the ANOM chart developed by Peter Wludyka. With the slice chart you create a one-way ANOM chart of one factor for each level of the second factor, making it much easier to visualize the interaction effects. John Noguera and Peter Wludyka extended the concept to binomial and Poisson data.
