Problem Selection: Fairfield Middle School is considering opening a snack store to run before and after school. The school needs help to determine the type of soft drinks, chips, candy, and cookies to sale to the students and staff. Using data analysis each group will be responsible for selecting the top two items to sale for each category.
 * Group A: Soft Drinks || Group B: Chips || Group C: Candy || Group D: Cookies ||
 * Cola || Potato Chips (Plain) || M&Ms || Oatmeal Cookies ||
 * Lime || BBQ chips || Starburst || Chocolate Chip Cookies ||
 * Grape || Sour Cream and Onion Chips || Skittles || Peanut Butter Cookies ||
 * Orange || Salt and Vinegar Chips || Fruit chewable || Sugar Cookies ||
 * Fruit Punch || Doritos || Jolly Ranchers || Macadamia Cookies ||

Reporting Category: Statistics Virginia SOL 6.15 the student will be able to: a). describe mean as balance point; and b) decide which measure of center is appropriate for a given purpose. SOL 6.14 The student, given a problem situation, will a) construct circle graphs; b) draw conclusions and make predictions, using circle graphs; and c) compare and contrast graphs that present information from the same data set.
