ANOVA and regression are mathematically equivalent in many cases, meaning that data analyzed with ANOVA can also be analyzed with regression, often yielding the same outcomes. This is because both techniques can assess the relationship between independent variables (which can be either categorical for ANOVA or continuous/categorical for regression) and a continuous dependent variable.
