COMPARING WAYS TO REPRESENT DATA.

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

Ages of golfers participating in a golf tournament:

$44,48,40,25,28,37,29,34,45,51,43,35,38,57,50,$
$35,47,30,63,43,44,60,46,43,33,45,42,34,32$

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.

$\begin{array} {c | c c c c c c c c c c c c} 2 & 5 & 8 & 9\\ 3 & 0 & 2 & 3 & 4 & 4 & 5 & 5 & 7 & 8\\ 4 & 0 & 2 & 3 & 3 & 3 & 4 & 4 & 5 & 5 & 6 & 7 & 8\\ 5 & 0 & 1 & 7\\ 6 & 0 & 3 \end{array}$

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

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.
