Cancer is a multifactorial disease, meaning it is influenced by numerous factors. For instance, researchers might be interested in studying the impact of a new drug (Factor A) across different age groups (Factor B) on tumor shrinkage. Two-Way ANOVA allows for the assessment of:
1. Main Effects: The individual impact of each independent variable on the dependent variable. 2. Interaction Effects: The combined impact of the two variables, which can reveal whether the effect of one factor depends on the level of the other.
