AP Statistics Score Predictor
Your Predicted AP Statistics Exam Results
MCQ Scaled Score: / 50
FRQ Scaled Score: / 30
Total Composite Score: / 80
Explanation: Your raw Multiple Choice (MCQ) score (out of 40) is scaled to 50 points. Your total raw Free Response Question (FRQ) score (sum of 6 questions, each out of 4, totaling 24 points) is scaled to 30 points. These scaled scores are added to get your Composite Score (out of 80). This composite score is then mapped to a predicted AP Score (1-5) based on historical cut scores.
| AP Score | Approximate Composite Score Range | Interpretation |
|---|---|---|
| 5 | 60 – 80 | Extremely well qualified |
| 4 | 48 – 59 | Well qualified |
| 3 | 36 – 47 | Qualified |
| 2 | 24 – 35 | Possibly qualified |
| 1 | 0 – 23 | No recommendation |
Note: These ranges are approximate and can vary slightly each year based on the College Board’s curve.

AP Stat Exam Calculator Formula and Mathematical Explanation
The AP Statistics exam is divided into two main sections: Multiple Choice (Section I) and Free Response (Section II). Each section contributes to a composite score, which is then converted into a final AP score (1-5). Our AP Stat Exam Calculator uses a standard weighting and scaling process to mimic the College Board’s methodology.
Step-by-Step Derivation of the AP Stat Exam Calculator Score
- Multiple Choice Raw Score: The AP Statistics exam typically has 40 multiple-choice questions. Each correct answer earns 1 point. There is no penalty for incorrect answers.
MCQ_Raw_Score = Number of Correct MCQs(out of 40) - Multiple Choice Scaled Score: The MCQ section accounts for 50% of the total composite score. The raw score is scaled to a maximum of 50 points.
MCQ_Scaled_Score = (MCQ_Raw_Score / 40) * 50 - Free Response Raw Score: The FRQ section consists of 6 questions: 5 short-answer questions and 1 investigative task. Each question is typically scored on a scale of 0-4 points.
FRQ_Raw_Score = Sum of scores for FRQ1 + FRQ2 + FRQ3 + FRQ4 + FRQ5 + Investigative Task(out of 24, since 6 questions * 4 points/question) - Free Response Scaled Score: The FRQ section accounts for the remaining 50% of the total composite score. The raw FRQ score is scaled to a maximum of 30 points.
FRQ_Scaled_Score = (FRQ_Raw_Score / 24) * 30 - Total Composite Score: The scaled scores from both sections are added together to form the total composite score.
Composite_Score = MCQ_Scaled_Score + FRQ_Scaled_Score(out of 80) - Predicted AP Score (1-5): The composite score is then converted into an AP score (1-5) using a predetermined cut score table. This table varies slightly each year but generally follows historical trends. Our AP Stat Exam Calculator uses an approximate historical table for this conversion.
