Understanding How the AP Statistics Exam is Scored

The AP Statistics exam is divided into two main sections, each contributing 50% to your final composite score. Understanding this weighting is crucial for developing a study strategy. The total composite score is typically calculated on a scale ranging up to approximately 100 points, which is then converted into the final 1-5 AP score.

Section I: Multiple Choice Questions (MCQ)

This section consists of 40 multiple-choice questions. Your raw score is simply the number of questions you answer correctly; there is no penalty for incorrect answers. To account for 50% of the total exam score, your raw MCQ score is multiplied by a weighting factor (typically 1.25), resulting in a maximum weighted score of 50 points for this section.

Section II: Free-Response Questions (FRQ)

The second section contains six free-response questions, which also account for 50% of the total score. These are graded by AP readers on a scale of 0 to 4 based on specific rubrics emphasizing statistical correctness, clarity, and communication.

• Questions 1-5: These are standard free-response questions. Together, they account for 37.5% of the total exam score (7.5% each).
• Question 6 (Investigative Task): This question is more complex and requires integrating knowledge from different parts of the course. It carries significantly more weight, accounting for 12.5% of the total exam score on its own.

How the Calculator Works

The AP Statistics Exam Score Calculator above uses standard weighting formulas to estimate your final score based on your inputs.

1. It takes your raw number of correct multiple-choice answers (out of 40) and applies the 1.25 multiplier.
2. It takes your individual scores (0-4) for the six free-response questions.
3. It applies a multiplier of approximately 1.875 to questions 1-5 and a higher multiplier of 3.125 to the Investigative Task (Q6) to calculate the weighted FRQ section score.
4. It sums the weighted MCQ and FRQ scores to determine a "Composite Score" out of 100.
5. Finally, it maps this composite score to an estimated 1-5 AP score based on historical scoring guidelines.

Historical Score Cutoffs

It is important to note that the College Board adjusts the "cutoffs" for each score (1, 2, 3, 4, or 5) every year based on the difficulty of that specific year's exam. Therefore, any calculator can only provide an approximation. Generally, a composite score above 60-65% is often required for a score of 5, while a score above 35-40% is typically needed to pass with a 3.
