Practice to Mastery

Twelve full-length practice exams. Every question original. Every answer explained.Practice to Mastery: AP® Statistics Practice Exams gives you twelve complete, exam-length rehearsals built to the structure of the current AP® Statistics exam and the official 2026 Course and Exam Description (CED). Each exam matches the real format: Section I has 42 multiple-choice questions in 90 minutes, and Section II has four 10-point free-response questions in 90 minutes, in the same order of question types you will see on test day. A graphing calculator is assumed throughout, just as on the actual exam.That adds up to 504 multiple-choice questions and 48 free-response questions, all written from scratch. Nothing is copied from released exams, and no item repeats a question from the companion Workbook, so every exam is a fresh test of what you know.WHAT EACH EXAM INCLUDES- Formulas and Tables pages at the front, modeled on the reference material provided on the exam: descriptive statistics, probability, sampling distributions and inferential formulas, plus standard normal, t, and chi-square tables.- Section I: 42 multiple-choice questions balanced across all five CED units, with shared-stimulus question sets built on tables, dotplots, boxplots, scatterplots, regression output, and software results.- Section II: four free-response questions covering the official question types, including one Inference question in every exam that asks you to carry out a complete procedure: hypotheses, conditions, calculations, and a conclusion in context.- A complete answer section: a detailed explanation for every multiple-choice question that shows why the correct answer is correct, and a point-by-point scoring guide for every free-response question with a full model response and notes on what does and does not earn credit.BUILT FOR ACCURACY AND REALISM- Content follows the CED’s five units: Exploring One-Variable Data and Collecting Data; Probability, Random Variables, and Probability Distributions; Inference for Categorical Data: Proportions; Inference for Quantitative Data: Means; and Regression Analysis.- Inference procedures rotate across the twelve exams: one- and two-sample z-procedures for proportions, one-sample, paired, and two-sample t-procedures, and chi-square tests of homogeneity and independence.- Every number has been checked with statistical software, every answer key has been audited independently, and answer positions are randomized so that no answer can be spotted by its length.- Contexts are realistic and varied, from wildfire management and veterinary clinics to robotics competitions and shipping logistics, so you practice reading unfamiliar scenarios the way the exam requires.HOW TO USE THIS BOOKTake an exam under timed conditions, score it with the answer key and scoring guides, and study every explanation, including those for questions you answered correctly.
