**Software for Exploratory Data Analysis and Statistical Modelling**, and kindly contributed to R-bloggers)One way analysis of variance models can be fitted to data using the R Commander GUI. The general approach is similar to fitting the other types of model in **R Commander** described in previous posts.

The **“Statistics”** menu provides access to some analysis of variance models via the **“Means”** sub-menu:

- One-way ANOVA – the simplest one-way analysis of variance model that can be applied to a set of data.

The **“Models”** menu provides access to various diagnostics for analysis of variance models via the **“Graphs”** sub-menu including:

- Basic diagnostic plots – four commonly used residual diagnostics including fitted values versus residuals and a normal probability plot for the residuals.

Other useful resources are provided on the Supplementary Material page.
