title: The Analysis of Variance (ANOVA).
abstract: This is the fourth in a series of articles devoted to a simplified description of experimental design, statistical analysis and interpretation. This article deals with a basic description of the analysis of variance (ANOVA) and its methods of computation and hypothesis testing. Examples are provided in which a one-way ANOVA is analyzed; methods for post-ANOVA pair-wise comparisons of treatment means are also discussed.
