Stats: Data and Models (3rd Edition)
We’ve been thrilled with the feedback we’ve received from instructors and students using Stats: Data and Models. If there is a single hallmark of this book it is that students actually read it. We have reports from every level—from high school to graduate school—that students find our books easy and even enjoyable to read. We strive for a conversational, approachable style, and introduce anecdotes to maintain students’ interest. And it works. Instructors report their amazement that students are voluntarily reading ahead of their assignments. Students write to tell us (to their amazement) that they actually enjoyed the book.
Unlike any other introductory book, Stats: Data and Models is written with the understanding that Statistics is practiced with technology. This insight informs everything from our choice of forms for equations (favoring intuitive forms over calculation forms) to our extensive use of real data. Most important, it allows us to focus on teaching Statistical Thinking rather than calculation. The questions that motivate each of our hundreds of examples are not “how do you find the answer?” but “how do you think about the answer?”
What’s New in This Edition
The third edition of Stats: Data and Models continues and extends the successful innovations pioneered in our books, teaching Statistics and statistical thinking as it is practiced today. We’ve rewritten sections throughout the book to make them clearer and more interesting. We’ve introduced new up-to-the-minute motivating examples throughout. And, we’ve added a number of new features, each with the goal of making it even easier for students to put the concepts of Statistics together into a coherent whole.
For Example. In every chapter, you’ll find new worked examples that illustrate how to apply new concepts and methods—more than 100 new illustrative examples. But these aren’t isolated examples. We carry the discussion through the chapter with each For Example, picking up the story and moving it forward as students learn to apply each new concept.
Exercises. We’ve added hundreds of new exercises, including more singleconcept exercises at the beginning of each set so students can be sure they have a clear understanding of each important topic before they’re asked to tie them all together in more comprehensive exercises. Continuing exercises have been updated with the most recent data. Whenever possible, the data are on the DVD and the book’s website so students can explore them further.
Step-by-Step Worked Examples. More than a third of the chapters have new or updated Think/Show/Tell Step-by-Step examples.
ActivStats Pointers. In the third edition, the ActivStats pointers have been revised for clarity and now indicate exactly what they are pointing to— activity, video, simulation, or animation—paralleling the book’s discussions to enhance learning.
Data Sources. Most of the data used in examples and exercises are from recent news stories, research articles, and other real-world sources. We’ve listed more of those sources in this edition.
New Motivating Examples. Each chapter starts with a real-world example, which we follow up with data analyses. We’ve updated and replaced many of these examples, introducing new stories (and data) about earthquakes, hurricane path prediction, penguin dives, belief in ghosts, motorcycle helmet compliance, whether men are less likely than women to wear seat belts, and Olympic speedskating.
Simulation. We’ve improved the discussion of simulation in Chapter 11 so it relates more easily to discussions of experimental design and probability. The simulations included in the ActivStats multimedia software on the book’s DVD carry those ideas forward in a student-friendly fashion.
Instructor’s Podcasts. (10 points in 10 minutes). Created and presented by the authors, these podcasts focus on key points in each chapter to help instructors prepare for class. They can be easily downloaded from the IRC.
