AP Statistics Question Types

Multiple Choice

Students are given exactly one hour and 30 minutes to complete the 40 questions in this part of the exam. Each question will be followed by five answer choices. At times, it may seem that there could be more than one possible correct answer. There is only one! Answers resulting from common mistakes are often included in the five answer choices to trap you.

Free Response

The AP Statistics free-response questions require not only that you perform the right computations but also that you communicate your reasoning and justify your answers clearly.

Investigative Task

As the name suggests, the investigative task question invites you to investigate a situation and arrive at a solution. It might also require you to expand your knowledge of statistics a bit beyond the course curriculum.

What is the calculator policy for the AP Statistics exam?

Students are expected to  bring a four function, scientific, or graphing calculator with statistical computation capability to use on both sections of the exam.

What’s on the AP Statistics formula sheet?

When you take the exam, you’ll be given a formula sheet with formulas and tables needed to complete exam questions.

What's a good AP Statistics score?

AP scores are reported from 1 to 5. Colleges are generally looking for a 4 or 5 on the AP Statistics exam, but some may grant credit for a 3. Each test is curved so scores vary from year to year Here’s how students scored on the AP Statistics exam in May 2022:
