Statistics: Informed Decisions Using Data helps you see the bigger picture and make informed choices for real-life situations such as buying a car, investing money, and choosing a place to live. It offers a practical emphasis that shows how statistics is connected not only to concepts, but to our world at large.
The 7th Edition adds a new set of Threaded Health and Nutrition Problems, drawing on National Health and Nutrition Examination Survey data obtained from the Centers for Disease Control and Prevention (CDC). This revision also adds a wealth of new and updated exercises, examples, and much more.
