AP Statistics Score Calculator (US Exam)

This exam multiplies each raw score instead of scaling whole sections: 40 questions at 1.25 make 50 points, 20 free-response points at 1.875 make 37.5, and the investigative task at 3.125 makes 12.5. The composite tops out at 100, split evenly between the two sections.

AP Statistics arrives at its composite differently from the other exams in this set: nothing is normalised section by section. Each raw score is multiplied by its own factor and the products are added up. A correct multiple-choice answer is worth 1.25, so all 40 make 50; each point on free-response questions 1 to 5 is worth 1.875, so the 20 available points make 37.5; and each point on question 6, the investigative task, is worth 3.125, so its 4 points make 12.5. The two sections still end up even at 50 apiece, and the maximum is 100. The defaults: 26 correct questions make 32.50, 12 points across questions 1 to 5 make 22.50, and 2 points on the task make 6.25 — a composite of 61.25 that rounds to 61 and sits between the 55 for a 4 and the 70 for a 5. The task earns its larger factor because it alone counts for a quarter of Section II while sharing the same 0-to-4 scale as the rest. Rounding cuts both ways: 30 correct questions with 13 free-response points and 2 on the task make 68.13, round to 68 and stay a 4. Two numbers here are undocumented — the 75-to-25 split inside Section II, and the cut scores 70, 55, 40 and 25, back-calculated estimates that move a few points per administration.
