Where Your Composite Falls
14.5 more composite points would move you up to a 4. Cutoffs are estimates and shift slightly each year.
A composite of 45.5 typically maps to an AP score of 3. College Board cutoffs are historical estimations.
How the AP Statistics Exam is Graded
The AP Statistics exam measures your understanding of data patterns, sampling, probability, and statistical inference. The exam consists of Section I (40 multiple-choice questions) and Section II (6 free-response questions, including 5 short questions and 1 investigative task).
Both sections carry equal weight (50% each). In the standard grading model, your multiple-choice raw score is multiplied by 1.25 to scale it up to 50 points. The free-response section is also scaled up to 50 points by scaling the short questions and investigative task respectively. This brings the maximum composite score to 100 points.
AP Score Cutoffs & Reference Bands
The composite score is mapped to the final AP score (1–5). Below are the typical cutoff ranges and the corresponding qualification labels:
| AP Score | Composite Point Range | Qualification Label |
|---|---|---|
| 5 | 75 – 100 | Extremely well qualified |
| 4 | 60 – 74 | Well qualified |
| 3 | 45 – 59 | Qualified (College Credit passing cutoff) |
| 2 | 33 – 44 | Possibly qualified |
| 1 | 0 – 32 | No recommendation |
Benchmark Section Targets for Success
To plan your study targets, refer to the typical multiple-choice correct count and free-response raw score pairings needed to reach each AP grade:
| Target AP Score | MCQ Correct / 40 | Raw FRQ Points / 26 | Estimated Composite |
|---|---|---|---|
| 5 | 34 correct | 18 points | 75 (5) |
| 4 | 29 correct | 14 points | 60 (4) |
| 3 | 24 correct | 9 points | 45 (3) |
| 2 | 18 correct | 6 points | 33 (2) |
AP Statistics Course Units
The AP Statistics course is organized into 9 units. Review the units and concepts covered:
- Unit 1: Exploring One-Variable Data: Representing and describing categorical and quantitative data, distributions, and the normal distribution model.
- Unit 2: Exploring Two-Variable Data: Representing and describing bivariate quantitative data, correlation, and linear regression.
- Unit 3: Collecting Data: Planning study designs, sampling methods, sources of bias, and experimental design.
- Unit 4: Probability, Random Variables, and Probability Distributions: Probability rules, independence, conditional probability, discrete random variables, and binomial/geometric distributions.
- Unit 5: Sampling Distributions: Central Limit Theorem, sampling distributions for proportions, and sampling distributions for means.
- Unit 6: Inference for Categorical Data: Proportions: Constructing and interpreting confidence intervals and performing significance tests for one or two proportions.
- Unit 7: Inference for Quantitative Data: Means: Constructing and interpreting confidence intervals and performing significance tests for one or two means.
- Unit 8: Inference for Categorical Data: Chi-Square: Chi-Square tests for goodness of fit, homogeneity, and independence.
- Unit 9: Inference for Quantitative Data: Slopes: Constructing confidence intervals and performing significance tests for the slope of a regression line.
Scoring Calculations & Mathematics
The composite score uses the following mathematical scaling:
Multiple Choice Score = Raw Correct × 1.0 (unweighted) or × 1.25 (weighted)
Raw FRQ Score = FRQ 1 + FRQ 2 + FRQ 3 + FRQ 4 + FRQ 5 + FRQ 6 (Max 26)
Composite Score = Multiple Choice Score + Raw FRQ Score (Max 100)
Worked Practice Examples
Example 1 — Safe Pass (AP Score 3)
28/40 Multiple Choice Correct · FRQs: 3, 3, 2.5, 3, 2, 4 · Unweighted Mode
Multiple Choice Score = 28.0 points
Raw FRQ Score = 3 + 3 + 2.5 + 3 + 2 + 4 = 17.5 points
Composite Score = 28.0 + 17.5 = 45.5 / 100
Predicted AP Score: 3 (Qualified)
Example 2 — Below Passing (AP Score 1)
18/40 Multiple Choice Correct · FRQs: 2, 1.5, 2, 2.5, 1, 3 · Unweighted Mode
Multiple Choice Score = 18.0 points
Raw FRQ Score = 2 + 1.5 + 2 + 2.5 + 1 + 3 = 12.0 points
Composite Score = 18.0 + 12.0 = 30.0 / 100
Predicted AP Score: 1 (No Recommendation)
Example 3 — Strong Pass (AP Score 4)
35/40 Multiple Choice Correct · FRQs: 4, 3.5, 4, 3.5, 4, 5.5 · Unweighted Mode
Multiple Choice Score = 35.0 points
Raw FRQ Score = 4 + 3.5 + 4 + 3.5 + 4 + 5.5 = 24.5 points
Composite Score = 35.0 + 24.5 = 59.5 / 100
Predicted AP Score: 4 (Well Qualified)
Frequently Asked Questions
- How is the AP Statistics composite score calculated?
- Your AP Statistics composite score is calculated out of a maximum of 100 points. In standard scoring, the multiple-choice section (40 questions) is scaled to 50% (multiplied by 1.25). The free-response section is also scaled to 50% (with the 5 short questions multiplied by 1.875 and the 1 investigative task multiplied by 2.083 to sum to 50 points). In unweighted raw sum mode, the raw MCQ count and raw FRQ sum are directly added.
- Are these AP Statistics score conversion ranges official?
- No. The College Board does not release exact score cutoff boundaries beforehand. Cutoffs are adjusted slightly each year based on exam difficulty and statistical scaling. The ranges used here (5: 75–100, 4: 60–74, 3: 45–59, 2: 33–44, 1: 0–32) represent widely accepted estimates based on historical practice exams.
- What is the weighting split between the Multiple Choice and FRQ sections?
- The AP Statistics exam is weighted equally: 50% for Multiple Choice and 50% for Free Response. Both sections contribute up to 50 points to the final 100-point composite score.
- Is there a penalty for incorrect answers on the AP Statistics exam?
- No. There is no guessing penalty on the AP Statistics exam. You only receive points for correct answers, so you should always select an answer for every multiple-choice question, even if you are not sure.
- What score is needed to earn college credit for AP Statistics?
- Most colleges and universities grant credit or advanced placement for a score of 4 or 5. Many public universities also accept a score of 3. You should check the specific credit policy database on the College Board website or your target university's registrar page.
- What is the difference between the first 5 FRQs and FRQ 6?
- The first 5 FRQs are short, focused questions (each graded out of 4 points) covering exploring data, sampling, probability, and inference. FRQ 6 is the Investigative Task (graded out of 6 points), which presents a novel statistical scenario requiring you to apply familiar concepts in a new context.
- What is the format of the AP Statistics exam?
- The exam is 3 hours long. Section I consists of 40 multiple-choice questions in 90 minutes. Section II consists of 6 free-response questions (5 short + 1 investigative task) in 90 minutes. Each section is worth 50% of your grade.
- Are calculators permitted on the AP Statistics exam?
- Yes. A graphing calculator with statistical capabilities (like the TI-84) is expected and allowed for the entire duration of the exam. Calculators must be on the College Board approved list.
- What are the key topics covered in the AP Statistics course?
- The course covers 9 units: Unit 1 (Exploring One-Variable Data), Unit 2 (Exploring Two-Variable Data), Unit 3 (Collecting Data), Unit 4 (Probability), Unit 5 (Sampling Distributions), Unit 6 (Inference for Categorical Data: Proportions), Unit 7 (Inference for Quantitative Data: Means), Unit 8 (Inference for Categorical Data: Chi-Square), and Unit 9 (Inference for Quantitative Data: Slopes).
- Can I earn partial credit on AP Statistics FRQs?
- Yes. AP readers score FRQs based on category levels: Essentially Correct (E), Partially Correct (P), and Incorrect (I). You can earn substantial partial points by explaining your reasoning, even if your final numerical answer contains a calculation error.
