**1. Write the data** as a set of ordered pairs.



 * 2. Change your window settings so that the x-values are between 0 and 10 and the y-values are between 0 and 10.**

This can't be done on the computer.
 * 3. Set scatter plot, List 1 as x-values, List 2 as y-values.**


 * 4. Use Graph to draw the scatter plot.**

Pg. 209 # 1-4
As age increases, the time decreases.
 * 1. Describe any patterns you see in the graph above.**


 * 2. Make a scatter plot of the following data.**

As the age increases, the time decreases, but then the time increases.
 * 3. Describe any patterns you see in the scatter plot.**

This scatter plot starts with slower times, and towards the end the times increase while in the other scatter plot, the scatter plot starts with faster times and get faster as the scatter plot ends.
 * 4. How does this scatter plot differ from scatter plot for the boys' time.**
