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.

Brase/Brase’s UNDERSTANDING BASIC STATISTICS, 8E, INTERNATIONAL METRIC EDITION provides instructors a streamlined and effective way to teach the essentials of statistics, including early coverage of regression, within a more limited timeframe. With simulation questions, labs, projects, news-sourced videos with questions, and more available in the online course, this solution includes an entire course package designed to teach students the basics of statistics and how to apply those to real-world situations. Help your students think statistically, overcome their apprehension about statistics, and learn to love a subject that once inspired anxiety. In this 8th Edition, International Metric Edition, students see the real-world significance of statistics and engage with new features that help them develop critical thinking and statistical literacy skills. The use of the graphing calculator, Microsoft® Excel®, MINITAB®, MINITAB EXPRESS, and SPSS® is covered but not required.

Overview of the Chi-Square Distribution. Chi-Square: Tests of Independence and of Homogeneity. Chi-Square: Goodness of Fit. Testing a Single Variance or Standard Deviation.

Part II: Inferences Relating to Linear Regression.

Inferences for Correlation and Regression.

- The chapter on Normal Curves and Sampling Distributions (Chapter 7) has been divided into two parts that give appropriate places for pause to review and summarize content. Each part has a brief introduction, brief summary, and list of chapter problems applicable to the part.
- New Terminology problems are included in the chapter problems. These problems are primarily true/false or multiple choice, highlighting some of the main features of terms or concepts.
- Brief discussions of Ethics in statistics (Section 1.3) based on guidelines recommended by the American Statistical Association; Appropriate use of P-values (Section 9.3) as discussed by the American Statistical Association; Data Science and Big Data (Using Technology, Chapter 2)
- Examples, guided exercises, and problem sets have been updated to reflect more recent real data and real-world scenarios.
- Updates in Technology sections include instructions for Excel 2013, Minitab 17, and the new Minitab Express.

- Coverage of the descriptive components of regression early in the text makes it easier to provide students with a thorough introduction to essential statistical concepts, and helps them to steadily build knowledge and improve their skills throughout the course. Inferences regarding regression are in a later section that can be covered after discussion of estimation (Section 8.1, 8.2) and hypothesis testing (Sections 9.1,9.2).
- 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.
- 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.
- "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.
