Understanding the Scoring System for the AP Statistics Exam

The scoring system for this assessment is split into two sections: multiple-choice questions and free-response questions. The multiple-choice section is worth 50% of the total score, while the free-response section contributes the other 50%. Each section is scored separately, and then combined to determine your final score.

For multiple-choice questions, each correct answer earns a point. Incorrect answers do not result in a penalty, meaning there is no negative marking. It’s important to answer all questions, even if you have to guess, since there’s no penalty for wrong answers.

In the free-response section, points are awarded for both the accuracy of your answers and the clarity of your reasoning. This section is scored holistically, meaning graders look at the overall quality of your response rather than awarding points for individual components. Be sure to show all necessary work and provide detailed explanations where required.

Scores are then converted into a final score on a scale from 1 to 5, with 5 being the highest. A score of 3 typically indicates a passing result, though each institution may set their own score requirements for credit or placement.
