Released AP Statistics questions are valuable, but the 2027 exam has a new course map and a new digital four-FRQ structure. Use historical questions to practice statistical reasoning, then crosswalk each question to the revised five-unit CED before deciding how much study time it deserves.
Which old questions still transfer well?
| Historical question type | 2027 value | Study action |
|---|---|---|
| Sampling, experiments, bias, scope | Strong transfer | Keep. These support Unit 1 and FRQ 1 reasoning. |
| Probability rules, binomial, Normal models | Strong transfer | Keep if the topic is in current Unit 2 scope. |
| One- and two-proportion inference | Strong transfer | Keep; update response style for typed 2027 FRQs. |
| One-sample, paired, two-sample t | Strong transfer | Keep; focus on conditions and contextual conclusions. |
| Regression description/residuals | Strong transfer | Keep descriptive/model reasoning. |
| Geometric distribution | Removed core | Skip as required 2027 exam preparation. |
| χ² goodness-of-fit | Removed core | Skip; do not confuse with homogeneity/independence. |
| Regression slope inference | Removed core | Do not treat as required 2027 content. |
| Old six-question FRQ set | Format mismatch | Use individual questions, not old-section pacing. |
Four steps before solving any released question
- 1
Label the current unit
If it no longer maps to one of the five units, check whether it was removed.
- 2
Label the statistical practice
Formulate, collect, analyze, interpret—or a combination.
- 3
Solve without copying the scoring language
Produce your own statistical argument before reading a rubric.
- 4
Convert to 2027 response habits
Type the final response and practice the current four-FRQ timing separately.
Historical questions are strongest when paired with current practice
Use old FRQs in three passes
Historical scoring guidelines are useful for seeing what statistical justification looks like, even though the 2027 questions use a new 10-point structure.
The new FRQ section is four 10-point questions in 90 minutes, so practice longer integrated reasoning and typed completion.
