Two-way ANOVA is a special case of the linear model. To measure an interaction effect, there must be multiple observationsįor some combination of factory and car model. ![]() The other two models is the same between factories. Has different gas mileage between factories, while the mileage of Is the difference in the mileage of the models (irrespective of theįactory) due to different design specifications. To the production methods between factories. One measure of interest is the difference in mileage due These two factors,įactory and model, explain the differences in mileage, that is, the The gas mileage in the cars can varyįrom factory to factory and from model to model. Suppose an automobile company has two factories, and each factory If the two factors have no interactions, the model is called an additive model. Response variable can depend on the group (level) of the other factor. These two factors can be independent,Īnd have no interaction effect, or the impact of one factor on the Two-way ANOVA is that in two-way ANOVA, the effects of two factors ![]() For an example, see Two-Way ANOVA for Unbalanced Design.Īs in one-way ANOVA, the data for a two-way ANOVA study canīe experimental or observational. To perform two-way ANOVA for an unbalanced design, You can use the function anova2 to perform a balanced two-way analysis Two-Way ANOVA Introduction to Two-Way ANOVA
