  1. 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
    See what is happening? Now, can you answer the question?
