How AP Statistics Scoring Works
The AP Statistics exam is a hybrid digital exam — MCQs on Bluebook, FRQs handwritten. It has two equally weighted sections, each worth 50% of your score. Total exam time is 3 hours. A formula sheet is provided. Graphing calculator required for both sections.
| Section | Questions | Time | Weight | Composite Pts |
|---|---|---|---|---|
| I: Multiple Choice | 40 questions (5 choices) | 90 min | 50% | 50 pts |
| II-A: FRQs 1-5 (Standard) | 5 questions × 4 pts | ~65 min | 37.5% | 37.5 pts |
| II-B: FRQ 6 (Investigative Task) | 1 question × 4 pts | ~25 min | 12.5% | 12.5 pts |
Composite Score Formula
MCQ Scaled = (Correct / 40) × 50. FRQ Scaled = (Total FRQ raw / 24) × 50. Composite = MCQ Scaled + FRQ Scaled, out of 100 total points.
FRQ Holistic Scoring Rubric
Unlike most AP exams, AP Statistics FRQs are graded holistically on a 0-4 scale rather than per-part. This means the quality and completeness of your overall response matters, not just individual pieces.
| Score | Descriptor | What It Means |
|---|---|---|
| 4 | Complete | Thorough understanding. Correct methods, calculations, and interpretations with proper context. |
| 3 | Substantial | Strong response with minor errors. Clear reasoning but may have small computational mistakes. |
| 2 | Developing | Partial understanding. Some correct elements but logical gaps or missing justifications. |
| 1 | Minimal | Very limited understanding. Incorrect application with minimal correct statistical reasoning. |
| 0 | No Credit | No response or completely incorrect with no understanding demonstrated. |
Unit Weights on the AP Statistics Exam
The exam covers 9 units. Units 1, 4, 6, and 7 together account for over half the exam. Focus your study time on these high-weight units, especially inference topics which appear on most FRQs.
2025 AP Statistics Score Distributions
In 2025, 267,690 students took the AP Statistics exam. The pass rate was 60.3% — consistent with recent years. AP Stats has one of the lower 5-rates (17.0%) among math/science APs, reflecting the exam's emphasis on communication and interpretation over pure computation.

Exam Strategies by Section
Multiple Choice
Read each question carefully — answers often use similar-sounding statistical terms. Eliminate wrong answers first. Use your graphing calculator for normalcdf/tcdf calculations. No penalty for guessing — answer every question. Budget ~2 min per question.
FRQs 1-5 (Standard)
Always write in complete sentences with context. State conditions for inference (Random, Normal, Independent). Show formulas with values plugged in. Include units. Name the test/interval you're using. Budget ~12-13 min each.
FRQ 6 (Investigative Task)
This is the hardest question and worth 25% of FRQ score. Read the entire question before starting. It combines multiple skills — don't panic if it seems unfamiliar. Show all work. Partial credit is generous. Budget 25-30 minutes.
Calculator Tips
Know these functions cold: 1-Var Stats, LinReg(a+bx), normalcdf, invNorm, tcdf, invT, χ²cdf. Store intermediate calculations in memory. Use STAT TESTS menu for hypothesis tests and confidence intervals. Practice with YOUR calculator.
