Author’s Note

In 1997, 7,667 students took the AP Statistics exam, and as enrollment in AP Statistics classes increased at a higher rate than in any other AP class, 184,572 students took the exam in 2014. The number of students required to take statistics in college has surpassed the number of students required to take calculus. High schools across the country have recognized this trend and are developing and expanding their statistics offerings. The new Common Core mathematics standards feature statistics and probability in a primary role throughout the high school curriculum. This Barron’s book is intended both as a topical review during the year and for final review in the weeks before the AP exam. Step-by-step solutions with detailed explanations are provided for the many illustrative examples and practice problems as well as for the six practice tests, including a diagnostic test.

Special thanks are due to Steve Hanson, Dave Bock, Lee Kucera, Dawn Dentato, Brendan Murphy, Daren Starnes, and Jane Viau for their many useful suggestions. Thanks to Linda Turner, senior editor at Barron’s, for her guidance. Thanks to my brother, Allan, my sons, Jonathan and Jeremy, my daughters-in-law, Cheryl and Asia, and my grandsons, Jaiden and Jordan, for their heartfelt love and support. Most thanks of all are due to my wife, Faith, whose love, warm encouragement, and always calm and optimistic perspective on life provide a home environment in which deadlines can be met and goals easily achieved.
