=Math Project=

The purpose of this research project is to dig a little deeper into the subject of U.S. car market sales. Based on the sales of a variety of different automobile brands in the always competitive American market during the months of January of 2008 and 2009, we will be able to interpret the information and analyze differences in sales between these two months. The project will also focus on interpreting several facts; such as the most popular brands in the market as well as the least popular, and which types of cars are the least and the most popular. We will also find out why the most popular companies sold so many cars, and why the least popular brands kept a low profile in sales.
