ANOVA was developed by the statistician Ronald Fisher. ANOVA is based on the law of total variance, where the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical …

The assumptions for ANOVA are 1. independent observations; 2. normality: the outcome variable must follow a normal distributionin each subpopulation. Normality is really only needed for small sample sizes, say n < 20 per group. 3. homogeneity: the variances within all subpopulations must be equal. Homogeneity is only needed if sample sizes are very...
