INTERACTIONS


Analysis of variance allows you to test not only for the individual variables but also for their combinations. This is an important concern. As you have noticed in previous discussions, combinations of variables sometimes have a different effect than you would expect from variables alone. That effect is important, and as experimenters we want to know about it. In statistical terms, we say that an interaction effect exists between variable X and variable Y.
