I can’t promise that I will cover it all, but it should help to know that ANOVAs are typically referred to as 1-way and 2-way, which is just a way of saying how many factors are being examined in the model. Like any statistical routine, ANOVA also comes with it’s own set of vocabulary. This tutorial explores both the features and functions of ANOVA as handled by R. Although ANOVA is relatively simple compared to many statistical models, there are still some ins and outs and what-have-yous to consider. While it is commonly used for categorical data, because ANOVA is a type of linear model it can be modified to include continuous data. ANOVA is one of the most basic yet powerful statistical models you have at your disopsal.
