ANOVA is used to determine if there is a significant difference between the means of two or more groups. It is a test that measures the variance between groups and within groups. The null hypothesis assumes that there is no difference between the means and that any observed differences are due to chance. The alternative hypothesis assumes that there is a significant difference between the means. Therefore, we are concerned with outcomes in which there is more variance between categories than within categories.
