AP Statistics Score Calculator
Enter your multiple-choice count and free-response points — including the investigative task — to estimate your AP Statistics composite and predicted 1–5.
AP Statistics is split 50/50 between multiple choice and free response. The twist is the sixth free-response question — the investigative task — which is weighted more heavily than the other five. This calculator applies the official weighting, including that heavier investigative task, to estimate your 1–5.
How AP Statistics is scored
Your 40 multiple-choice questions scale to 50 points. On the free-response side, Questions 1–5 (20 raw points) are multiplied by 1.875 and the investigative task (Q6, 0–4) by 3.125, together making the other 50 points.
FRQ scaled = (Q1–5 points × 1.875) + (Q6 × 3.125)
Composite = MC scaled + FRQ scaled
| Section | Raw | Weight |
|---|---|---|
| Multiple choice | 40 questions | 50% |
| Free-response Q1–5 | 0–4 each (20) | 37.5% |
| Investigative task (Q6) | 0–4 | 12.5% |
Composite score to AP score (estimated)
College Board doesn't publish official cut scores, and they move a little each year. These are commonly cited estimates from recent exams.
| AP Score | Composite (out of 100) |
|---|---|
| 5 | 71 – 100 |
| 4 | 62 – 70 |
| 3 | 51 – 61 |
| 2 | 41 – 50 |
| 1 | 0 – 40 |
Worked example
30 of 40 multiple choice, 14 of 20 on Questions 1–5, and 3 of 4 on the investigative task:
| MC = 30 × 1.25 | 37.5 |
| FRQ = (14 × 1.875) + (3 × 3.125) | 35.6 |
| Composite = 37.5 + 35.6 | 73.1 → score of 5 |
Why the investigative task matters
Because Q6 is weighted at 3.125 points each versus 1.875 for the other questions, a strong investigative task is worth noticeably more than a strong regular question. It rewards showing a complete statistical process — stating assumptions, doing the analysis, and communicating a conclusion in context — so it's worth budgeting extra time for.
