A large standard deviation occurs when the data has a large spread of data points.
This might happen with the heights of students in grades K - 12
A small standard deviation might be the heights of students in grade K.
b) will have both larger prize amounts than a and smaller prize amounts than a.
400 700 1000 1300 1600
a) 900 950 1000 1050 1100
