You'll learn about the common misconceptions about statistics that people make, allowing you to better use statistics in your own work. Reinforcing your learning, you'll review lists of real-life examples or applications of a concept or, for more advanced concepts, read complete solutions to statistical problems that include actual calculator and spreadsheet results and illustrate how you can apply the concept to your own problems.You'll also be able to 'test yourself' at the end of a chapter to review the concepts and methods that you learned in the chapter.
