##### Features & benefits

**Making Informed Decisions**: Mike Sullivan helps students connect statistical concepts with their everyday lives, teaching them to think critically and make informed decisions.

**Putting It Together**—found in chapter openers, sections, and exercises—connects concepts from different chapters to show statistics as a whole, rather than a series of disconnected procedures. These are indexed at the beginning of the book for easy reference.**Making an Informed Decision**chapter openers pose a question, and then present the statistical concept necessary for prudent decision-making. This feature engages the reader in the statistical-thinking process and highlights the practicality of statistics.

**Checking Understanding** opportunities appear throughout each section and at the end of every chapter for students to test their knowledge.

**Explaining the Concepts**exercises follow**Vocabulary & Skill Building**and**Applying the Concepts**exercises at the end of each section. These new exercises ask the student to go beyond applying the concepts and explain their results in written form.**Preparing for this Section**quizzes verify that students have the prerequisite knowledge for the next section, and include page numbers for quick reference.
