Statistics: Learning From Data, 2nd edition, addresses common problems faced by students and instructors with an innovative approach to elementary statistics. The organization by Learning Objective, focus on real-data examples, and adherence to the Guidelines for Assessment and Instruction in Statistics Education (GAISE) help students learn to think like statisticians.

Features
  • Read It links under each question quickly jump to the corresponding section of a complete, interactive eBook that lets students highlight and take notes as they read.
  • Master It Tutorials (MI) are available for all major concepts and guide students step by step through the solution of a problem.
  • 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 the 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: 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.
