Comparing Two Data Sets In Exercises 43– 48, find the coefficient of variation for each of the two data sets. Then compare the results.

Ages and Heights The ages (in years) and heights (in inches) of all pitchers for the 2013 St. Louis Cardinals are listed. (Source: Major League Baseball)

Solution:

Step 1 of 3:

The given data set is

Ages |
24 |
29 |
37 |
24 |
26 |
25 |
24 |
32 |
22 |
29 |
23 |
31 |

Heights |
72 |
76 |
73 |
73 |
77 |
76 |
72 |
74 |
75 |
75 |
74 |
79 |

Here we have to find the coefficient of variation for each of the two data sets and to compare the results.
