Boys Maximum Presidential Mile Time:

**1.**//Describe any patterns you see in the scatter plot you made in the example above.//
I see that the older you are, the faster you need to be while running the mile to get presidential. I saw this because the speed needed for the presidential award decreases as the age increases. At the end of the graph, though, the times get closer and closer.

Girls Maximum Presidential Mile Time:

 * 2.**

**3.**//Describe any patterns you see in the scatter plot.//
From 10 years old to 12 years old, there are giant gaps in speed, bigger than for boys. At 12 years old, the gaps get smaller. Then, at 14 years old, you can get slower but still get the presidental mile time. at about 16 years old though, you have to speed up again. The pattern in this graph is very unpredictable.

**4.**//How does this scatter plot differ from the scatter plot for the boys' times?//
The girls graph is way more unpredictable than the boys graph. In the girls graph, there is a point where you can be slower. In the boys graph, you have to keep on continuing to improve your times, even though you can slow your progress, you cant go backwards like you can in the girls graph.
