A one-way analysis of variance (ANOVA) is used when there is one categorical independent variable and one continuous dependent variable. In this situation, the categorical variable is the corporations and the continuous variable is the dollar amount of United Way contributions. Therefore, a one-way ANOVA is the most appropriate model for comparing the contributions made by sales people from the three retail corporations.
