Understanding AP Statistics FRQs
The free-response section accounts for 50% of your total AP Statistics score and consists of six questions completed in 90 minutes. Unlike multiple-choice questions, FRQs require you to show your work, explain your reasoning, and communicate statistical concepts clearly in context.
FRQ Question Types
Questions 1-5 (Short-Answer Questions): Each designed to be completed in approximately 12 minutes, these questions typically focus on specific skill categories. Question 1 often emphasizes collecting data through surveys and experiments. Question 2 centers on exploring data using graphs and summary statistics. Question 3 tests probability and sampling distributions. Question 4 focuses on statistical inference. Question 5 combines multiple skills from earlier questions.
Question 6 (Investigative Task): This extended question requires approximately 30 minutes and assesses your ability to apply statistical concepts in non-routine ways or novel contexts. It integrates multiple skill categories and content areas, testing your deeper understanding and analytical flexibility.
Scoring Tip: Your explanation is often worth as much as the correct answer itself. College Board graders award points for proper statistical reasoning, correct methodology, accurate calculations, and clear communication. Always justify your answers with appropriate statistical language and context from the problem.

Frequently Asked Questions
How should I pace myself during the free-response section?
The AP Statistics exam provides 90 minutes for six free-response questions. Plan to spend approximately 12 minutes on each of the first five short-answer questions and reserve 30 minutes for Question 6, the investigative task. However, you are not required to answer questions in order. If a particular question seems more challenging, move to the next one and return later with fresh perspective.
Do I need to show all my calculations on FRQs?
Yes, showing your work is essential for earning full credit on AP Statistics free-response questions. Graders award points for proper setup, correct formulas, accurate calculations, and appropriate conclusions stated in context. Even if your final answer is correct, you may lose points without sufficient justification and explanation of your statistical reasoning.
Can I use a calculator on all parts of the FRQ section?
Yes, you may use an approved graphing calculator throughout the entire free-response section. Your calculator can help with complex calculations, statistical tests, and creating plots. However, you must still show the setup for your work and cannot simply write "calculator says" as your answer. Reference specific calculator functions when appropriate, such as stating you performed a "2-sample t-test" on your calculator.
What should I do if I run out of time on an FRQ?
If time runs short, prioritize earning partial credit by completing the parts you know well and writing brief but clear explanations for remaining parts. Graders use rubrics that award points for each component, so partial responses can still earn substantial credit. Avoid leaving questions completely blank—even a thoughtful setup or partial calculation demonstrates understanding and may earn points.
Should I practice older FRQs from before 2019?
Questions from before the 2019 Course and Exam Description update (1997-2018) remain valuable practice materials, as the statistical concepts and skills tested are fundamentally the same. However, prioritize practicing with 2021-2025 questions first to familiarize yourself with current question formatting and emphasis. Older questions provide additional practice volume once you've mastered recent exam patterns.
Where can I find the scoring guidelines for these questions?
Each PDF document linked in this collection includes not only the free-response questions but also official scoring guidelines, sample student responses at different score levels, and scoring distributions. These materials are invaluable for understanding what graders expect and how to structure your responses to earn maximum credit.
Pro Study Strategy: After completing each practice FRQ, carefully review the scoring guidelines before moving to the next question. Pay special attention to the "Essentially Correct" and "Partially Correct" criteria for each part. This immediate feedback helps you internalize what strong responses look like and improves your statistical communication skills more effectively than practicing multiple questions without review.
