Overview
The poorer you are the more likely you are to be obese. To further examine the economic and calorie choices consumers face the prices and calorie content of food is determine by calories and their respective price. With this information the price could be averaged out to find how much does dollar 1 cost in calories. Fast Food is the staple of fast, cheap and unhealthy food. With the three chains of fast food restaurants, the dollar per calories is determined. Which of the fast food chains, McDonald, Burger King or KFC offers the most bang for your buck?
Ten products are tested by their calories and determine what is the average amount of calories for the fast food chains. These products are regular day items in their menu, whether breakfast sandwiches, burgers, fries, and ice cream. Comparing what the highest calorie foods are and what they are made of and whether if that is a good option or not.

Answers
1. The fast food chains are the independent variable because they do not change.
2. The calories are dependent variables they are dependent upon the type of fast food chain, what food it is and where it came from.

The bar graph shows that McDonald has a higher distribution of calories per dollar when i graphed the data of Calories divided by dollars to get how much each dollar equals calories.
Conclusion
The conclusion of this data is that McDonald offers the most calories per dollar. Whether or not it is healthy is a different situation. Through the bar graph, and scatter plot we can see that McDonald has a higher curve and larger distribution than KFC and Burger King. Even the IQR, 1st quartile, 3rd quartile, median, and mean all shows that McDonald has the highest amount of calories per dollar.
