ANOVA (Analysis of variance) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among group means in a sample.

ANOVA is a form of statistical hypothesis testing heavily used in the analysis of experimental data. In the ANOVA setting, the observed variance in a particular variable is partitioned into components attributable to different sources of variation.
