- It helps determine if there are significant interactions between the two independent variables and if each independent variable has a significant main effect.
- Useful when studying how two factors simultaneously influence the dependent variable.
- Allows for comparison of means across multiple groups formed by the combinations of the two independent variables.
- Helps in understanding whether the effects observed are due to one variable, the other, or both.
