AP Statistics 2023 FRQ: A Deep Dive into the Exam’s Structure, Tips, and Practice Problems
The College Board’s Advanced Placement (AP) Statistics exam is a rigorous assessment that evaluates students’ knowledge and skills in statistics. The 2023 exam will be administered on Friday, May 12th, and will consist of two sections: multiple choice and free response (FRQ).
Exam Structure
The multiple choice section comprises 40 questions and lasts for 90 minutes, while the FRQ section includes six questions and lasts for 105 minutes. The free response questions are divided into two parts:
- Part A: Two questions worth 10 points each
- Part B: Four questions worth 15 points each
Students must answer all six FRQ questions and demonstrate their ability to:
- Apply statistical methods to solve real-world problems
- Analyze and interpret data
- Draw valid conclusions and generalizations
Scoring
The multiple choice section accounts for 50% of the overall exam score, and the FRQ section accounts for the remaining 50%. Each part of the FRQ section is scored independently, with a maximum score of 10 points for Part A and 15 points for Part B questions.
Tips for Success
To excel in the AP Statistics 2023 FRQ, students should:
- Master the fundamentals: Thoroughly review the entire AP Statistics curriculum, focusing on key concepts such as probability, sampling, and inference.
- Practice routinely: Solve numerous FRQ-style problems to develop proficiency in applying statistical methods.
- Time management: Carefully allocate time during the exam to ensure adequate completion of all questions.
- Show your work: Clearly demonstrate your reasoning and calculations in the FRQ responses.
- Be concise and clear: Use precise language and organize your answers logically.
Practice Problems
Part A
- A researcher wants to determine if there is a relationship between the number of hours students spend studying and their final exam score. She collects data from a sample of 50 students and performs a regression analysis. The regression model is:
Final Score = 70 + 0.5(Study Hours)
a) Interpret the slope of the regression line.
b) Predict the final score of a student who studies for 10 hours.
Part B
- A company claims that its new product will reduce customer wait time by an average of 10 minutes. A random sample of 25 customers is surveyed before and after using the product. The average wait time before using the product is 15 minutes, and the average wait time after using the product is 12 minutes.
a) State the appropriate hypotheses for testing the company’s claim.
b) Perform a hypothesis test using a significance level of 0.05.
c) Draw a conclusion based on the results of the hypothesis test.
