Introduction to the Practice of Statistics (IPS), 9th edition, by David S. Moore, George P. McCabe, and Bruce A. Craig shows students how to produce and interpret data from real-world contexts—doing the same type of data gathering and analysis that working statisticians in all kinds of businesses and institutions do every day. With this phenomenally successful approach originally developed by David Moore and George McCabe, statistics is more than just a collection of techniques and formulas. Instead, students develop a systematic way of thinking about data, with a focus on problem-solving that helps them understand statistical concepts and master statistical reasoning.

Features:
  • Every WebAssign question links to applicable chapters in a fully integrated eBook.
  • Learning Curve adaptive quizzing available for every chapter.
  • StatTutors provide multimedia tutorials with built-in assessments that explore important statistics concepts and procedures.
  • Video Technology Manuals provide brief instructions for using specific statistical software (over 50 topics/videos per software) and are available for TI-83/84 calculators, JMP, Excel, Minitab, SPSS, R, and RCmdr.
  • Statistical Videos consist of StatClips, StatClips Examples, Statistically Speaking "Snapshots," and StatBoards, including animated lecture videos, whiteboard lessons, and documentary-style footage that illustrate key statistical concepts and help students visualize statistics in real-world scenarios.
  • Associated data files from the textbook are available to use for appropriate exercises, formatted for TI-83/84 calculators, JMP, Excel, Minitab, SPSS, R, and RCmdr.
  • Downloadable test banks and practice quizzes for each chapter.
  • Book specific PowerPoint lecture slides and iClicker slides.
  • Instructor and student solution manuals.
Many questions from this textbook are available in WebAssign. The online questions are identical to the textbook questions except for minor wording changes necessary for Web use. Whenever possible, variables, numbers, or words have been randomized so that each student receives a unique version of the question. This list is updated nightly.
