AP Statistics Score Calculator 2026
Enter your section scores for AP Statistics to estimate your 1–5 AP score.
Estimate. The College Board does not publish composite cutoffs, so these lines are reconstructed from released exams and third-party curves. Treat it as a prediction, not a guarantee.
AP Statistics is half multiple choice, half free response, but the free response isn't graded like a math test. It's graded on communication: a right number with no explanation often scores below a wrong number with sound reasoning. And one question, the Investigative Task, is quietly worth far more than the others.
Inside the AP Statistics exam
Three hours, split 50/50 for a composite out of 100. Section I is 40 multiple-choice questions in 90 minutes, each scaled up, with no penalty for guessing. Section II is six free responses in 90 minutes: five shorter questions and a longer Investigative Task at the end. The Investigative Task carries the most weight of any single free response, roughly a sixth of your whole score, so don't run out of time before you reach it.
How the AP Statistics score is calculated
AP Statistics combines these sections into one composite out of 100:
- Multiple choice: out of 40, weighted 50% of the composite.
- Free response: out of 24, weighted 50% of the composite.
Estimated score ranges
- 5: composite ≈ 70–100
- 4: composite ≈ 57–69
- 3: composite ≈ 44–56
- 2: composite ≈ 33–43
- 1: composite below 33
These ranges are estimates from past released exams. Use them to see how close you are to the next score, not as an official guarantee.
How to squeeze out more points
- Answer in context every time. "There is a positive linear association between hours studied and score" beats a bare r-value; the rubric rewards the sentence, not just the statistic.
- Name the procedure and check its conditions. Before a test or interval, state which one and verify the conditions (random, normal, independent); skipping that caps the question.
- Budget for the Investigative Task. It's the heaviest single question, so leave it real time rather than letting questions 1 to 5 eat the clock.
- Define your symbols. Saying what p or mu represents in the actual situation is a routine, easy point students forget.
Where students lose points
- Giving a number with no interpretation. Statistics free responses are scored on communication, so an unexplained answer earns partial credit at best.
- Skipping the conditions check before a test. The rubric expects you to justify that the procedure is appropriate before you run it.
- Forgetting the Investigative Task weight. It's worth more than a regular question, so a rushed or blank Q6 hurts more than a rough Q2.
- Vague conclusions. "Reject the null" alone isn't enough; tie it back to the claim in plain language about the real context.
A worked example
On AP Pass-style curves a composite near 70 of 100 has landed a 5, with a 3 closer to 44. Enter 30 of 40 multiple choice plus your marks on the five short questions and the Investigative Task above, and notice how much the composite shifts when you change the Task, since it carries extra weight.

Frequently asked questions
- How is the AP Statistics exam scored?
- Each section is weighted into a composite out of 100: Multiple choice out of 40 (50%); Free response out of 24 (50%). The composite then maps to a 1–5 score.
- What composite do I need for a 5 on AP Statistics?
- On our estimated curve, roughly 70+ (out of 100) is a 5, 57+ is a 4, 44+ is a 3, and 33+ is a 2. These shift slightly every year.
- Is this the official AP curve?
- No. The College Board equates each administration to keep scores comparable across years, and it does not publish the composite cutoffs. These lines are reconstructed from released exams and widely-cited third-party curves, so treat them as an estimate.
- What is a good AP score?
- A 3 is considered qualified and earns credit at many colleges; 4s and 5s are strong and accepted more widely, including at selective schools.
- Why is the Investigative Task weighted more?
- It rewards extended reasoning, so question 6 is scaled higher than questions 1 to 5, roughly a sixth of the whole exam. Leave it real time; a strong Task lifts your composite more than a strong short question.
- Do I really lose points for not explaining a correct answer?
- Often, yes. Statistics free responses are scored on communication, so a right number with no interpretation in context usually earns partial credit while a well-reasoned answer scores higher.
