"As a statistics teacher, I'm always on the lookout for accessible yet challenging problems for students to chew on in class. The problems in this book are wonderful: they're clear, they test important concepts in statistics, and they require insight without being tricky." — Andrew Gelman, Professor of Statistics and Political Science, Columbia University, Author of Active Statistics: Stories, Games, Problems"Writing great test questions can among the most challenging aspects of teaching. We draw on Smith’s collection extensively in our “Calling Bullshit” course on data reasoning. Perhaps I should not disclose the source of my exam questions — but if any of my students choose to seek an advantage by reading Smith’s book from cover to cover, they’ll learn more by doing so than I could hope to teach them in a quarter." — Carl T. Bergstrom, Professor of Biology, University of Washington, Author of Calling Bullshit: The Art of Skepticism in a Data-Driven World"A treasure-trove; a gold mine! Buy this book if you want questions that require critical thinking (rather than multiple-choice guessing). Hundreds of questions and answers carefully organized by topic. Every one teaching introductory statistics should own a copy of this book!" — Milo Shield, American Statistical Association Fellow, Visiting Professor, New College of Florida, Author of Statistical Literacy and Editor of www.StatLit.org"Most professors can write tests that measure knowledge, but Gary Smith's questions often go well beyond this to measure a student's ability to use this knowledge. What a remarkable collection of superb thought-provoking questions!" — Woody Studenmund, Professor of Economics, Occidental College, Author of Using Econometrics"The unique features of these exam questions are their origins in everyday life and insights into ferreting whether students know the subject and can apply it in nonrobotic ways. I wish I had access to this test bank when I began teaching." — William E. Becker, Professor Emeritus of Economics, Indiana University, Past Editor, The Journal of Economics Education"Professor Smith's questions draw upon interesting real-world scenarios to test students' understanding of key statistical concepts. I wish I had had this collection when I first started teaching statistics!" — Alan Reifman, Professor of Human Development & Family Sciences, Texas Tech University, Author of Hot Hand: The Statistics Behind Sports' Greatest Streaks
