Practice to Mastery: AP® Statistics Workbook is a complete, course-aligned question bank for students who want to build real fluency before exam day, not just skim a review.Organized around the five units of the current AP Statistics Course and Exam Description, the workbook contains 722 original multiple-choice questions and 28 free-response questions, every one with a detailed solution. Each unit opens with a clear list of the topics it covers, then works through carefully sequenced questions labeled Easy, Medium, or Hard, so you can start where you are and climb to exam-level difficulty.What’s inside:- Unit 1, Seeing the Shape of Data: displays, summary statistics, percentiles and z-scores, outlier rules, sampling methods, bias, and experimental design- Unit 2, Modeling Chance: two-way tables, probability rules, conditional probability, discrete random variables, binomial and normal models, simulation, and sampling distributions- Unit 3, Evidence from Counts: confidence intervals and significance tests for one and two proportions, Type I and Type II errors, power, and chi-square tests for homogeneity and independence- Unit 4, Evidence from Measurements: t-intervals and t-tests for one mean, paired data, and two means, with careful attention to conditions- Unit 5, Lines Through the Data: scatterplots, correlation, least-squares regression, residuals, residual plots, and the coefficient of determination- A full-length practice exam in the current format: 42 multiple-choice questions and 4 free-response questions, with answers, scoring guides, and a score estimateBuilt the way the exam is built. Questions use realistic contexts, two-way tables, computer and calculator output, dotplots, histograms, boxplots, scatterplots, and residual plots. Shared-stimulus question sets mirror the exam’s format, and cross-unit questions train you to combine ideas, just as the free-response section demands. Vocabulary, condition checks, procedure names, and conclusion wording follow the Course and Exam Description closely, so the habits you practice are the habits that earn points.Explanations that teach. Every multiple-choice answer comes with a step-by-step explanation of why the correct answer is right: the method, the setup with numbers, each calculation, and a conclusion written in context, with generic calculator functions named where they help. Each free-response question includes a point-by-point scoring guide in the style used on the exam, showing what earns each point and what typical responses fall short, followed by a complete model solution.Use it your way:- Work unit by unit alongside your class, or target the topics where you lose points- Move from Easy to Hard within each unit to build confidence and speed- Practice writing complete inference procedures: hypotheses, parameters, conditions, test statistics, p-values, and conclusions- Finish with the practice exam under timed conditions and estimate your AP scoreAccurate and original. Every statistic, interval, test statistic, and p-value was independently recomputed, and every answer key was checked by a separate review. All questions, data sets, and contexts are original to this book.Ideal for high school students taking AP Statistics, students preparing on their own, and teachers looking for a large bank of exam-style practice with complete solutions. For final review, pair it with the companion volume, Practice to Mastery: AP® Statistics Practice Exams, which offers full-length practice exams in the current format with detailed explanations and scoring guides.AP® is a trademark registered by the College Board, which is not affiliated with, and does not endorse, this product.
