2-79.

COMPARING WAYS TO REPRESENT DATA.

Use the golf-tournament data below to complete parts (a) through (e).

Ages of golfers participating in a golf tournament:

   
   

  1. Use the data to create a dot plot.

    Your dot plot may look like the one below. 

  2. Why is a dot plot not the best choice for graphing this data?

    Explain in your own words.

  3. Create a stem-and-leaf plot for the data.

    Below the stem is the first column.  The leaves are represented by the other columns.

  4. Use the stem-and-leaf plot to create a histogram for the data.

    A histogram labeled, Age, on the horizontal axis, scaled in equal segments of 10, from 0 to 70.  Frequency is labeled on the vertical axis, scaled by twos from 0 to 12. Starting at the left, each segment has the following bar heights: 0, 0, 3, 9, 12, 3, 2.

  5. What range of ages do most golfers fall between? Do you see any ages that are much larger or smaller than other ages?

  • Look at the plots and histogram you created to help you answer these questions.
