For courses in Introductory Statistics.

### Gets students to do statistics actively as they learn

**Interactive Statistics: Informed Decisions Using Data, 2nd Edition** presents content in a way that gets students actively doing statistics as they encounter new concepts. Written fully in MyLab Statistics, it combines text, multimedia and assessment into a seamless learning experience. Through a series of Interactive Assignments, students are encouraged to experience statistics in new and dynamic ways. This practical approach paired with the interactive, guided learning environment helps improve conceptual understanding, knowledge retention and ability to connect statistics to the world at large.

### Hallmark features of this title

**Interactive Assignments**for each section of a chapter cycle through a “read a little, watch a little, do a little” model. Students read text, interact with multimedia and step-by-step examples, and complete assessment questions for each objective.**Preparing for This Section**provides review and exercises to assess mastery of prerequisite topics.**Learning Objectives for This Section**previews the learning objectives in the Interactive Assignment.

### Features of MyLab Statistics for the 2nd Edition

**NEW - StatCrunch Question Library:**This library of questions provides opportunities for students to analyze and interpret data sets in StatCrunch.- Instructors can assign individual questions from the library by topic or they can assign questions from the same data set as a longer assignment that spans multiple learning objectives.

**NEW - Pre-built Learning Catalytics modules**for each chapter and more questions:- Learning Catalytics is a student response tool that uses smartphones, tablets or laptops to engage students in more interactive tasks and thinking during lecture. It fosters student engagement and peer-to-peer learning with real-time analytics.

### About our authors

**Michael Sullivan, III** has training in mathematics, statistics and economics, with a varied teaching background that includes 27 years of instruction in both high school- and college-level mathematics. He is currently a full-time professor of mathematics at Joliet Junior College. Michael has numerous textbooks in publication, including an Introductory Statistics series and a Precalculus series which he writes with his father, Michael Sullivan.

Michael believes that his experiences writing texts for college-level math and statistics courses give him a unique perspective on where students are headed once they leave the developmental mathematics tract. This experience is reflected in the philosophy and presentation of his developmental text series. When not in the classroom or writing, Michael enjoys spending time with his 3 children, Michael, Kevin and Marissa, and playing golf. Now that his 2 sons are getting older, he has the opportunity to do both at the same time!

**George Woodbury **earned a bachelor's degree in Mathematics from the University of California - Santa Barbara and a master's degree in Mathematics from California State University - Northridge. He currently teaches at College of the Sequoias in Visalia, CA, just outside of Fresno. George has been honored as an instructor by both his students and his colleagues. Aside from teaching and writing, George served as the department chair of the math/engineering division from 1999 through 2004. He has been a user of MyLab Math and MyLab Statistics since inception, continually coming up with creative ways to integrate his teaching methods with technology. He actively blogs his thoughts on math, statistics, teaching and study skills.
