The Practice of Statistics for the AP® Course, Eighth Edition, is fully aligned to the new AP® Statistics Course and Exam Description (CED) launching for the 2026–2027 school year. Authored by beloved AP® Statistics educators Daren Starnes and Josh Tabor - and trusted by more teachers than any other program, TPS 8e offers the clarity, structure, and support teachers need to navigate this new curriculum shift with confidence.
Organized into five units that match the new CED, the textbook features revised formulas, updated nomenclature, and new exercise styles that mirror the redesigned AP® Exam. Multi-focus problems reinforce multiple statistical practices, while “See Yourself in Stats” career profiles help students see the relevance of statistics beyond the classroom.
TPS 8e builds on the trusted pedagogy teachers know and love—engaging examples, scaffolded practice, AP® Exam Tips, and robust problem sets—now enhanced with unit-level projects and expanded tech support, including Desmos and NumWorks (in Achieve).
Whether you’re new to teaching AP® Stats or returning with experience, TPS 8e provides expert guidance from real classroom teachers—backed by a comprehensive suite of print and digital tools designed for success on the new AP® Statistics Exam.
