From May 2027, AP Statistics has 42 multiple-choice questions (50% of your score) and four 10-point free-response questions (12.5% each). Every rubric point is earned independently. College Board publishes no cut scores, but on our estimate a 5 needs a weighted composite of about 70%, for example 31/42 on multiple choice with 7, 7, 7, 6 on the free response.
AP Statistics exam format (May 2027)
3 hours · Fully digital in Bluebook from May 2027 (built-in Desmos; a handheld graphing calculator is still allowed). The course revision effective 2026–27 changed the exam: multiple choice goes from 40 to 42 questions with four answer choices, and free response from six questions (including the investigative task) to four 10-point questions weighted 12.5% each.
| Part | Raw points | Weight |
|---|---|---|
| Multiple choice (of 42) | 0–42 | 50% |
| FRQ 1 (0–10) | 0–10 | 12.5% |
| FRQ 2 (0–10) | 0–10 | 12.5% |
| FRQ 3 Inference (0–10) | 0–10 | 12.5% |
| FRQ 4 (0–10) | 0–10 | 12.5% |
Estimated score cutoffs
| AP score | Weighted composite | 2026 students | 2025 students |
|---|---|---|---|
| 5 | 70%+ | 17% | 17% |
| 4 | 55–70% | 23% | 21.4% |
| 3 | 40–55% | 22% | 21.9% |
| 2 | 25–40% | 17% | 15.9% |
| 1 | 0–25% | 21% | 23.7% |
How this estimate works: each section counts at the weight in College Board's Course and Exam Description, and each free-response question counts in proportion to its rubric points because College Board publishes only the section weight. The 70/55/40/25% cutoffs are our round-number estimates. College Board publishes no composite cutoffs and says AP exams are not curved: cut scores are set in standard-setting studies, so the distribution above shows how students did, not where the lines sit. Wrong multiple-choice answers cost nothing.
How to use this AP Statistics score calculator
- Enter how many of the 42 multiple-choice questions you expect to get right. Leave out wrong or blank answers, since they cost nothing.
- Score Question 1 (collecting data and forming investigative questions) out of 10. Count one point for every rubric row you think you fully met.
- Score Question 2 (analyzing and interpreting data) out of 10.
- Score Question 3, the inference question (a hypothesis test or a confidence interval), out of 10. Go through it step by step: variables, procedure, hypotheses or parameter, conditions, calculation, conclusion.
- Score Question 4, the multi-part question that spans several units, out of 10.
- Read the estimated score and the gap to the next line. If you are grading a practice test, share the link so your teacher sees the same breakdown.
AP Statistics units and exam weighting (2026-27 course)
The revised course folds the old units into five. The weightings below apply to the multiple-choice section. Free-response questions are organized by skill, not by unit.
| Unit | Multiple-choice weighting |
|---|---|
| 1. Exploring One-Variable Data and Collecting Data | 20–30% |
| 2. Probability, Random Variables, and Probability Distributions | 15–25% |
| 3. Inference for Categorical Data: Proportions | 15–25% |
| 4. Inference for Quantitative Data: Means | 10–20% |
| 5. Regression Analysis | 10–20% |
The multiple-choice section is also weighted by statistical practice: Formulate Questions 5–10%, Collect Data 20–30%, Analyze Data 25–35%, Interpret Results 25–35%. Along with single questions, the section includes question sets, several questions built on one shared scenario.
AP Statistics FRQ scoring (new 10-point format)
The four questions always appear in the same order. Each is worth 10 points on an analytic scale. College Board's sample scoring guidelines split every question into ten separate rows worth 0 or 1 point, and each point is earned on its own. That is very different from the old exam, which had six 4-point questions.
Question 1: Multi-Focus on Practices 1 and 2
This question covers formulating questions and collecting data. In the sample, you identify sampling methods, explain whether results generalize to a population, pick and justify a graph for given summary statistics, describe a distribution's likely shape, and write a valid investigative question. That last part earns several separate points, one for each required component of the question.
Question 2: Multi-Focus on Practices 3 and 4
This question covers analyzing data and interpreting results. The sample asks you to identify information, decide whether outliers exist, compare numerical summaries, and then decide whether a claim holds and justify that decision. The decision and the justification are separate points.
Question 3: Inference
This is a full hypothesis test or confidence interval. In the sample (a two-sample z-test for proportions), the ten rows are: identify the variables, classify the variables, identify the procedure, state the hypotheses, define the parameters, check the randomization and 10% conditions, check the normality or expected-counts condition, calculate the test statistic and p-value, compare the p-value with the significance level, and justify the conclusion in context. Because every step has its own point, getting the arithmetic wrong still leaves most of the question available.
Question 4: Multi-Focus on Practices 2, 3, and 4
This multi-part question mixes content areas. The sample moves from probability and a sample mean taken from a table to choosing and carrying out an inference procedure, with its conclusion. Some pairs of points can be earned in either order.
Worked examples
Solid 4. 30/42 multiple choice gives 35.7 composite points. FRQs of 7, 6, 5, 6 (total 24/40) add 30.0. The composite is 65.7%, an estimated 4.
Borderline 5. 31/42 multiple choice (36.9) plus FRQs of 7, 7, 7, 6 (33.7) gives 70.7%, an estimated 5. With one fewer FRQ point the composite would be 69.4%.
| Total FRQ points (of 40) | Multiple-choice correct needed for an estimated 5 |
|---|---|
| 20 | 38 of 42 |
| 24 | 34 of 42 |
| 28 | 30 of 42 |
| 32 | 26 of 42 |
| 36 | 21 of 42 |
AP Statistics score distribution history
These figures come from College Board's past distributions page. Every year shown was taken on the old format (40 multiple choice, six free-response questions including the investigative task), so treat them as a rough guide for 2027.
| Year | Scored 5 | Scored 3 or higher |
|---|---|---|
| 2026 | 17% | 62% |
| 2025 | 17% | 60.3% |
| 2024 | 17.5% | 61.8% |
| 2023 | 15.1% | 60% |
| 2022 | 14.8% | 60.4% |
| 2021 | 16.2% | 57.9% |
| 2019 | 14.7% | 59.7% |
Over this period the share of 5s has stayed between about 15% and 18%, and roughly six in ten students scored 3 or higher. The 2025 exam had 266,791 test takers, with a mean score of 2.92.
May 2027 exam date
AP Central lists AP Statistics for Tuesday, May 11, 2027 (session 2). This is the first year the exam is fully digital, and you submit free-response answers in Bluebook, not in a paper booklet. Printed reference materials are mailed to schools and are also available in Bluebook.
How to earn more points on the AP Statistics exam
- Write every inference step. Question 3 gives a point each for hypotheses, parameters, each group of conditions, the calculation, and the conclusion. A correct p-value alone earns one row out of ten.
- Name the parameter in context. Say "the true proportion of adults like those in the study who would text the code." Just writing "p" is not enough.
- Justify, don't just decide. Several rows split "decides whether a claim is supported" from "justifies it with the statistics". Make one explicit comparison, such as the p-value against alpha or the mean against the median.
- Learn the three parts of an investigative question. In the sample Question 1, separate points go to the variables, to the population parameters together with the direction of the alternative hypothesis, and to the population. A vague question loses these points one at a time.
- Answer every multiple-choice question. There are four choices and no penalty, and each question is worth about 1.2% of your composite.

Frequently asked questions
What do you need for a 5 on AP Statistics?
College Board does not publish cutoffs. This calculator uses 70% of the weighted composite as its estimate. On the May 2027 format that could be 31/42 multiple choice plus FRQ scores of 7, 7, 7, 6 out of 10, which gives about 70.7%. In 2026, 17% of AP Statistics students earned a 5.
How many questions are on the 2027 AP Statistics exam?
42 multiple-choice questions in 90 minutes and 4 free-response questions in 90 minutes. The old exam had 40 multiple-choice questions and 6 free-response questions, including the investigative task.
How is each AP Statistics FRQ scored in 2027?
Each of the four questions is worth 10 points on an analytic scale. In College Board's sample scoring guidelines each point is a separate 0-or-1 row, earned independently, so a mistake in one part does not automatically cost you the points in the others.
Is the investigative task still on AP Statistics?
No. The course revision effective for 2026-27 cut the free-response section from six questions to four, and the investigative task was removed. Question 4 is now a multi-part question that combines several content areas.
How much is one AP Statistics free-response point worth?
Each FRQ is 12.5% of the exam over 10 points, so one rubric point is 1.25 composite points. One multiple-choice question is 50/42, about 1.2 composite points, so one FRQ point is worth slightly more than one multiple-choice question.
Can I use a calculator on the AP Statistics exam?
Yes. The Course and Exam Description says a graphing calculator with statistical capabilities is expected for both sections, and formulas and tables are provided for both sections. The exam is fully digital in Bluebook from May 2027.
When is the 2027 AP Statistics exam?
College Board lists the AP Statistics exam for Tuesday, May 11, 2027, in session 2. Check the AP exam start-times page for your time zone.
Are past AP Statistics score distributions comparable to 2027?
Only loosely. Distributions through 2026 come from the old format with six free-response questions. May 2027 is the first exam on the new 42-question, four-FRQ format, so its results may look different.
