Running out of time before the AP Statistics exam? This last-minute cram guide covers the inference procedures that appear every year, the "in context" FRQ requirements, and what to memorize before you walk in.
AP Statistics Exam Structure
Section I: 40 MCQ in 90 minutes (50% of score). Section II: 6 FRQs in 90 minutes (50%) — 5 short FRQs (4 pts each) plus the 12-point Investigative Task.
Inference Procedures to Know Cold
- One-sample t-test and t-interval: Always check conditions (random, normal/large sample, independent). Know the test statistic formula and what df to use.
- Two-sample t-test and t-interval: "Random" condition means two independent random samples or random assignment to treatments.
- Chi-square goodness-of-fit: Tests whether observed counts match expected counts. Expected counts must each be ≥ 5.
- Chi-square test for independence: Tests association between two categorical variables in a two-way table.
- Linear regression t-test: Tests H₀: β = 0. Know the conditions (LINER: Linear, Independent, Normal residuals, Equal spread, Random).
The "In Context" Rule
Every statistical conclusion on the FRQ section must reference the specific scenario — name the variables, population, or study from the problem. "We reject H₀" is worth 0 points. "We have sufficient evidence to conclude that the mean resting heart rate for marathon runners is less than 60 bpm" earns full credit.
