Overview
AP® Statistics is often the most abstract, applied mathematics course one will have taken. It combines intense mathematical skills with real-world situations to analyze the data of everyday life. It may be difficult to get used to at first, but with some proper studying you can master the course.
For practice problems and one-on-one tutoring, see the AP® Statistics Tutoring Page.

Tips
Formulas
AP Statistics has a formula sheet that also includes various tables relating to the course. While it may be helpful to memorize some of these formulas, they are all given for the entirety of the exam.
Consider Application
Problems in statistics use the same general concepts but are manipulated into a variety of situations. It is important to gain experience and be able to recognize certain situations and what concepts are needed in order to properly answer the questions.
Test Weighting
The official expected weighting of the exam can be used to help guide you through which subjects to place the most emphasis on.
Watch Videos
One of the biggest opportunities to learn that many neglect is watching videos of others working out problems. While some problems can fit into a formula, many cannot, and require problem solving skills. Watching others work out problems can be very beneficial to understanding how to approach certain types of problems.
Practice Past AP® Exams
The College Board officially publishes most of the AP® Exams in past years as well as solutions to all problems. These can be a very helpful study tool to utilize when preparing for the AP® Exam.
