Kokoska's data analysis approach in Introductory Statistics: A Problem Solving Approach, 2nd edition, moves students away from formulas and number-crunching, focusing instead on how working statisticians in a variety of fields collect and analyze data and use the results to tackle real-world problems. The WebAssign component for this text engages students with immediate feedback, an interactive eBook with online resources, and a question bank of end-of-section exercises.

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, and Statistically Speaking "Snapshots," 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.
• Book specific PowerPoint lecture slides and iClicker slides.
