Understanding Basic Statistics, 7th edition offers instructors an effective way to teach the essentials of statistics, including early coverage of regression, within a more limited time frame. 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 WebAssign component of this text engages students with immediate feedback, lecture videos, and a complete eBook.

## Features

• Read It links under each question quickly jump to the corresponding section of a complete eBook that also contains links to videos and tutorials to help students learn the concepts.
• Course Packs with ready-to-use assignments built by subject matter experts specifically for this textbook. They are designed to save you time, and can be easily customized to meet your teaching goals. Course Packs are also available for Stats in Practice Video Questions, Labs, and Project Milestones.
• Stats in Practice Video Questions (SIP): Show students how Statistics applies in the real world. Short and current news videos introduce each chapter. Each video is accompanied by multiple-choice and discussion questions, so that students can understand real-world context of what they're learning and stay engaged throughout the whole chapter.
• Simulation Questions by JMP (JMP): Have your students understand concepts by utilizing real data. Students must discover the answer to guided questions by interacting with a simulation of real data in our JMP interactive applet within WebAssign.
• Concept Questions (CQ): Provide a new way of engaging with non-computational questions. Students enter a free response before they choose a multiple-choice answer, closing the gap between homework and test preparedness.
• Labs (Lab): Students can perform real statistical analysis in class or online with premade and chapter-specific Stats Labs. Require students to use the instructor-selected data analysis tool to analyze a real data set - pulling together knowledge learned from that chapter and previous material to facilitate whole-picture learning.
• Project Milestones (PJT): Allow one place for students to ideate, collaborate, and submit a longer-term project.The four sequential milestones are:
1. Research Design
2. Gather Data
3. Analyze Data
4. Present Results
• Test Banks (TB): A pool of over 1000 assessments for use in quizzes, tests, and exams.
• Student Resources include Data Analysis Tool Instructions / Tech Guides for the below software. Can be used stand-alone or in conjunction with assessment items (Homework, Labs, or Project Milestones).
• TI-83/84 and TI-Nspire Calculator
• Excel
• JMP
• Minitab
• SPSS
• R
• Instructor Resources include Instructional Lecture Videos, hosted by Dana Mosely. These topic-specific videos provide explanations of key concepts, examples, and applications in a lecture-based format.
