Analysis of variance (ANOVA) is a statistical technique designed to compare normally distributed, independent datasets by testing whether or not three or more population means are equal to one another. One-way ANOVA compares multiple groups against one independent variable, while factorial (two-way) ANOVA compares multiple groups against two independent variables. One risk of ANOVA is that there is an inflated chance for a type I error; however, the Bonferroni adjustment corrects this inflation.
