True or false: Linear regression is a categorical data mining model.

• A. False
• B. True
• C. Sometimes
• D. Not Applicable

Answer: (A)

Linear regression predicts a continuous numeric value by modeling a linear relationship between features and the target. Categorical data mining models assign observations to distinct categories or class labels. If the outcome is a category, you’d use a classifier (for example, logistic regression for binary classes), not linear regression. Encoding categories as numbers for a linear regression target can create meaningless distances and unreliable predictions. So the statement is false.
