A categorical variable is a type of variable that represents distinct categories or groups without any inherent numerical value. These variables can be nominal, where the categories have no specific order, or ordinal, where they can be arranged in a meaningful sequence. Understanding categorical variables is essential for effective variable selection and model building, as they can significantly impact the choice of statistical methods and interpretation of results.
