The exam is three hours long and covers a one-semester introductory non-calculus-based college course in statistics. In Section I of the exam, students are given 90 minutes to answer 40 multiple-choice questions on a wide variety of topics. In Section II, they must answer several free-response questions; each exam contains four to seven open-ended questions designed to be answered in about 10 minutes each, and a longer investigative task for which 30 minutes is allotted. The following major topics are covered: exploring data (describing patterns and departures from patterns); sampling and experimentation (planning and conducting a study); anticipating patterns (producing models using probability and simulation); and statistical inference (estimating population parameters and testing hypotheses).
Ideally, students should have access to a computer for work both in and out of the classroom. While it is not yet possible to have access to a computer during the AP Statistics Exam, standard computer output may be provided, and students will be expected to interpret it.
For sample multiple-choice questions, refer to the Course Description.
