Once you've practiced and mastered the basics of data analysis, graphs and statistics, as presented in Chapter 7, think about how you can apply these skills to real data. Refer back to page 363, the first page of Chapter 7, in your Basic Mathematics textbook and review the caloric intake versus body weight application.

Here's your chance to explore the World Wide Web and practice your new skills at the same time. Follow some related food and recipe Web sites and calculate the potential weight consequences of eating too much of your favorite foods.

After you've practiced and after you've explored, don't forget about your upcoming Chapter Test. Prepare for your exam by working through our Chapter 7 Review, and then check your answers. These free downloadable files are accessible by selecting the Chapter Review button at the top of this page.

Good luck!
