Children going back to school can be expensive for parents— second only to the Christmas holiday season in terms of spending (San Luis Obispo Tribune, August 18, 2005). Parents spend an average of $ 444 on their children at the beginning of the school year, stocking up on clothes, notebooks, and even iPods. However, not every parent spends the same amount of money. Imagine a data set consisting of the amount spent at the beginning of the school year for each student at a particular elementary school. Would it have a large or a small standard deviation? Explain. |
