Keisha surveyed a group of people to find their age and their shoe size. She then graphed the order pairs (age, shoe size) for each person. Which of the scatter plots most likely represents her graph?
Scatter plot I shows points approximating a line decreasing from the upper left to the bottom right.
Scatter plot I I shows points with no approximate pattern.
Scatter plot I I I shows points approximating a line increasing form the bottom left to the upper right.
A. Graph I
B. Graph II
C. Graph III.

It is difficult to determine without seeing the actual data, but a scatter plot of age and shoe size would likely show a positive correlation (as age increases, shoe size increases), so the scatter plot that best represents this pattern is Graph III. Therefore, the answer is C.
