AP Statistics Score Calculator

How It Works

AP Statistics has two parts: Section I (Multiple Choice) with 40 questions, and Section II (Free Response) with five short-answer questions plus one investigative task, totaling 26 points by default.

Default weights are MCQ 50%, FRQ 50%. You can adjust weights, totals, and the scoring curve in Advanced Settings.

We compute a weighted raw percentage and map it to a 1–5 estimate using adjustable score bands. The exact AP curve varies each year based on exam difficulty and overall student performance.

Inputs Explained

• MCQ Correct and Total: Enter the number of multiple choice questions you answered correctly out of 40 (default). You can change the total if you used a different practice test.
• Q1-Q5 Short Answer: Enter points earned (0-4 each by default) for the five short-answer questions. These typically cover exploratory data analysis, sampling and experimentation, probability, and statistical inference.
• Q6 Investigative Task: Enter points earned (0-6 by default) for the comprehensive investigative task that requires statistical reasoning across multiple concepts.
• Advanced Settings: Adjust section weights (must sum to 100%), edit FRQ totals if your rubric differs, and customize score band thresholds to match a specific curve.

Example Calculation

Let's walk through a sample calculation:

• MCQ: 28 out of 40 → 28 ÷ 40 = 70.0%
• FRQs: 3 + 3 + 3 + 2 + 3 + 5 = 19 out of 26 → 19 ÷ 26 ≈ 73.1%

Using the default weights (MCQ 50%, FRQ 50%), the weighted raw percentage is:

(0.700 × 0.50) + (0.731 × 0.50) ≈ 0.715 = 71.5%

With the default curve, 71.5% falls into the 60-74% range, yielding an estimated score of 3.

Tips & Notes

• Curves Change Yearly: College Board adjusts the curve annually based on overall performance. Treat this calculator as a study guide, not a prediction of your actual score.
• FRQ Strategy: For FRQs, clearly define variables, justify statistical conditions (normality, independence, randomness), interpret results in context, and show calculator steps where required. Small rubric gains can significantly impact your overall estimate.
• Master Key Topics: Practice sampling distributions, confidence intervals, hypothesis testing, and probability. Read questions carefully for context and direction of causality (experiment vs. observational study).
• Calculator Proficiency: Be comfortable with your calculator's statistics functions (confidence intervals, hypothesis tests, regression, probability distributions). Show what you entered and interpret the output.
• Communicate Clearly: On FRQs, write complete sentences, define parameters in context, and connect statistical conclusions to the real-world scenario. Partial credit is awarded for correct reasoning even with calculation errors.
