# Statistics Plain and Simple, 3rd Edition

### Overview

This straightforward, concise, conversational introduction to statistics presents a plain-and-simple overview of statistics that is sparing in its use of jargon. Readers develop a strong awareness of the interaction between statistical methods and research methods along with a solid working knowledge of basic statistical cautions in research design, an understanding of the concept of significance, and the critical thinking skills necessary to apply these ideas. Available with InfoTrac® Student Collections http://gocengage.com/infotrac.

### Features and Benefits

• Several modules include coverage of statistical power and effect size. Students learn how to increase power when using statistical tests and how to determine the effect size for t tests and ANOVAs.
• "In Review" tables occur frequently within each module, reinforcing students' learning and facilitating review. For example, the "Hypothesis Testing Table" summarizes the concepts of null hypothesis, alternative hypothesis (or research hypothesis), two-tailed (or non directional) tests, one-tailed (or directional) tests, Type I Error, Type II error, and statistical significance. The "In Review" table for "The t Test" provides a description and an example of the estimated standard error (or the mean), the t test, the one-tailed t test and the two-tailed t test.
• "Critical Thinking Checks" (after every "In Review" table) help students solidify their grasp of the core concepts presented and ensure that they understand before moving on.
• Glossary terms and definitions appear in the margins throughout the text to help students easily identify key terms for review.
• TI-83 exercises (and new TI-84 examples) show students how to use their calculators to solve a problem they have previously worked by hand.
• The end of each module includes a "Summary Review Table," "Critical Thinking Check" items (with answers), a review of key terms, and "Module Exercises." At the end of each chapter, a detailed self-test lets students check their understanding of the concepts, helping to prepare them for exams.
