Interpreting interactions is important in analyzing data generated by the ANOVA family of techniques. In this article, we examine how to specify the cell means used to describe an interaction. Although most researchers utilize the raw means that are the output of most analysis packages, R. Rosenthal and R. L. Rosnow suggest an alternative procedure, removing the treatment effects (and possibly the grand means) from the group means and then examining the interaction in isolation. We examine why and under what circumstances it is appropriate to use residual means to examine interactions. How the use of raw means versus residual means affects interpreting interactions is examined in the context of a demonstration experiment. After that, a procedure for interpreting interactions is presented
