AP Statistics Multiple-Choice

Single-select questions are each followed by five possible responses, only one of which is correct. 

AP Statistics Free Response Questions

The free response section consists of six multi-part questions, which require you to write out your solutions, showing your work. Unlike the multiple-choice section, which is scored by a computer, the free-response section is graded by high school and college teachers. They have guidelines for awarding partial credit, so you may still receive partial points should you not correctly respond to every part of  the question.

Can you use a calculator on the AP Statistics exam?

You are allowed to use a calculator on the entire AP Stats Exam—including both the multiple-choice and free-response sections. Scientific or graphing calculators may be used, provided that they don’t have any unapproved features or capabilities (a list of approved graphing calculators is available on the College Board’s website ).
