Analysis of variance (ANOVA), a technique included in many introductory statistics courses, analyzes the relationship between a quantitative dependent variable and one or more independent qualitative variables. The nature of the relationship is expressed in a model with unknown parameters. Many textbooks emphasize the mechanics of the technique while the model and its parameters remain abstractions or theoretical entities. We introduce a java applet that allows a student to profitably explore the features and factors of one and two-way ANOVA tables together with representational models and model parameters.
