Which choice best describes the claim implied by the statement that the model has high predictive accuracy?

• A. The model has low predictive accuracy.
• B. The model has high predictive accuracy.
• C. The model's predictions are unreliable.
• D. The model's usefulness is unclear.

Answer: (B)

High predictive accuracy means the model’s predictions align with actual outcomes most of the time. Saying the model has high predictive accuracy directly asserts that its predictions are correct at a high rate, typically measured as the proportion of correct predictions among all predictions. So the implied claim is simply that the model performs well on its predictive task. The other ideas—low accuracy, unreliable predictions, or usefulness being unclear—don’t fit because they describe opposite or unrelated aspects rather than the rate of correct predictions.
