Stay on current Cengage site**WebAssign** is a powerful digital solution designed by educators to help students learn maths and science, not just do homework. Instructors get the flexibility to define mastery thresholds and manage student learning aids down to the question level giving students the support they need to learn when they need it. **WebAssign** provides extensive content, instant assessment, and superior support.

**MindTap** is a personalised teaching and learning experience with relevant assignments that guide students to analyse, apply, and improve thinking, allowing you to measure skills and outcomes with ease.

Help students overcome their apprehension about statistics with Brase and Brase's UNDERSTANDING BASIC STATISTICS, ENHANCED, 7E, INTERNATIONAL METRIC EDITION. A condensed and more streamlined version of the same authors' bestselling UNDERSTANDABLE STATISTICS, 11E, this book offers instructors an effective way to teach the essentials of statistics, including early coverage of regression, within a more limited time frame. Thorough yet abbreviated, the text helps students realize the real-world significance of statistics, and offers an accessible exposition and a complete technology package. The Seventh Edition addresses the growing importance of developing students' critical thinking and statistical literacy skills with critical thinking features and new exercises throughout the text. The use of the graphing calculator, Microsoft® Excel®, MINITAB®, and SPSS® is covered but not required. The text is packaged with JMP® statistical software.

- New copies of the text are packaged with JMP® statistical software.
- "What Does . . . Tell Us?" and "Important Features of a . . ." provide brief, just-in-time summaries of key concepts.
- New examples and exercises help to keep the material fresh, timely, and relevant.
- The book's exposition has been tightened and simplified wherever possible.

- Guided exercises immediately follow selected examples and provide an opportunity for students to explore new concepts. Step-by-step solutions accompanying each exercise allow for immediate self-evaluation and reinforcement.
- Up-to-date technology-related examples include instruction appropriate for the latest versions of MINITAB®, SPSS®, and Excel®. Denoted by icons in the text, "Tech Notes" provide best practices and accompanying screenshots to assist students who are using these programs. "Using Technology" sections at the end of each chapter present problems with real-world data from a variety of disciplines.
- Critical Thinking boxes at the end of most sections help students hone their critical thinking skills by providing additional clarification on specific statistical concepts as a safeguard against incorrect evaluation of information.
- Interpretation boxes in several chapters help students refine their critical thinking and analysis skills by providing them with practice in explaining their statistical results in the context of a particular application.
- "Expand Your Knowledge" problems present the geometric mean and the harmonic mean, moving averages, correlation of averages, odds for and odds against, uniform probability distribution, plus four methods for confidence intervals, probability of two confidence intervals, and serial correlation.
- Special margin notes draw attention to more information about a related topic that appears in the "Expand Your Knowledge" exercises at the end of the section, allowing you to cover additional material as desired and enabling students to learn more about topics they find especially interesting or difficult to grasp.
