Peck and Olsen’s INTRODUCTION TO STATISTICS AND DATA ANALYSIS, 7th Edition helps you develop the ability to think statistically through its focus on conceptual understanding, use of real data and interpretation and communication of statistical information. Graphical displays of complex data sets are now common both online and in print media, and it is important to be able to interpret these types of displays. The 7th edition contains a new section on graphical displays of multivariable data, with a focus on extracting information and learning from them. WebAssign for Statistics accompanies this text. Designed by educators, WebAssign helps you learn not just do homework. WebAssign grants access to the ebook, assessments and analytics to enable you to be a selfsufficient learner and help you succeed in your course.

Roxy Peck
Roxy Peck is Associate Dean Emerita of the College of Science and Mathematics, and Professor of Statistics Emerita at California Polytechnic State University, San Luis Obispo. A faculty member at Cal Poly from 1979 until 2009, Roxy served for six years as Chair of the Statistics Department before becoming Associate Dean, a position she held for 13 years. She received an M.S. in Mathematics and a Ph.D. in Applied Statistics from the University of California, Riverside. Roxy is nationally known in the area of statistics education, and she was presented with the Lifetime Achievement Award in Statistics Education at the U.S. Conference on Teaching Statistics in 2009. In 2003, she received the American Statistical Association’s Founder’s Award, recognizing her contributions to K–12 and undergraduate statistics education. She is a Fellow of the American Statistical Association and an elected member of the International Statistics Institute. Roxy served for five years as the Chief Reader for the Advanced Placement (AP) Statistics Exam and has chaired the American Statistical Association’s Joint Committee with the National Council of Teachers of Mathematics on Curriculum in Statistics and Probability for Grades K–12 and the Section on Statistics Education. In addition to her texts in introductory statistics, Roxy is also coeditor of “Statistical Case Studies: A Collaboration Between Academe and Industry” and a member of the editorial board for “Statistics: A Guide to the Unknown, 4th Edition.” Outside the classroom, Roxy likes to travel and spends her spare time reading mystery novels.

ACCESSIBLE NARRATIVE. A more informal writing style accommodates a broader range of student reading levels.

UPDATED EXAMPLES AND EXERCISES. In a continuing effort to keep things interesting and relevant, the 6th Edition contains many updated examples and exercises that use data from recent journal articles, newspapers, and the web on topics of interest to students.

NEW SECTIONS ON RANDOMIZATIONBASED INFERENCE METHODS. Research indicates that randomizationbased instruction in statistical inference may help learners to better understand the concepts of confidence and significance. The 6th Edition includes new optional sections on randomizationbased inference methods. These methods are also particularly useful in that they provide an alternative method of analysis that can be used when the conditions required for normal distributionbased inference are not met. Each of the inference methods (Chapters 9 through 11) include new optional sections on randomizationbased inference that include bootstrap methods for simulationbased confidence intervals and randomization tests of hypotheses. These new sections are accompanied by online Shiny apps, which can be used to construct bootstrap confidence intervals and to carry out randomization tests.

NEW COAUTHOR. Tom Short joins the author team for the 6th edition. Tom is an Associate Professor at West Chester University of Pennsylvania, and brings a wealth of experience in teaching introductory statistics.

HELPFUL HINTS. Helpful hints in exercises direct students to relevant examples in the text and help students who may be having trouble getting started.

REAL DATA. Authentic scenarios with real data help students understand statistical concepts in interesting contexts that relate to their own lives.

Margin Notes, including "Understanding the context," "Consider the data," "Formulate a plan," "Do the work," and "Interpret the results" appear in appropriate places in the examples to highlight the importance of context and to increase student awareness of the steps in the data analysis process.

"Interpreting and Communicating the Results of Statistical Analysis" sectionswhich emphasize the importance of being able to interpret statistical output and communicate its meaning to nonstatisticianshave assignable endofsection questions associated with them.

The book emphasizes graphical display as a necessary component of data analysis and provides broad coverage of sampling, survey design, experimental design and transformations, and nonlinear regression.

Online material on logistic regression and nonparametric (distributionfree) methods give you the option of covering these topics if you wish. There is also expanded coverage of advanced topics in multiple regression and analysis of variance that can be used to support a more extensive coverage of the material currently appearing in print in Chapters 14 and 15.

Chapterending Technology Notes on JMP, Minitab, SPSS, Microsoft Excel 2007, TI83/84, and TInspire provide helpful hints and guidance on completing tasks associated with a particular chapter, as well as display screens to help students visualize and better understand the steps. More complete technology manuals are available on the text website.

For instructors who prefer a briefer and more informal treatment of probability, two chapters previously from the book, "Statistics: The Exploration and Analysis of Data" by Roxy Peck and Jay Devore are available as a custom option. Please contact your Cengage Learning Consultant for more information about this alternative and other alternative customized options available to you. (See the information listed below under the heading “Alternate TOC” for specific coverage in the two chapters.)
