35 multiple-choice questions in College Board exam style. Each has four choices and a full explanation of why each option is right or wrong.

Interpret slope and intercept in context, with the variables and their units.
Residual = observed − predicted. Check residual plots for patterns before trusting a linear model.
Correlation is not causation, and don't extrapolate: and read the explanations even when you got it right.
