A two-way ANOVA requires the dependent variable to have an interval/ratio level of measurement. This is because ANOVA tests the differences between means, and interval/ratio data allows for meaningful comparisons of the numerical values. Nominal or ordinal data cannot be used in ANOVA as they lack numerical values and do not allow for meaningful comparisons of the numerical values. Therefore, the dependent variable must be measured at an interval/ratio level.
