Lines and curves of best fit, scatterplot interpretation, predictions.
Two-variable data questions expect you to fit a linear or exponential model to a scatterplot and make predictions from the model while understanding when a prediction is unreliable.
These are real practice questions pulled from our Digital SAT bank. Try each one before reading the highlighted correct answer.
