The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude? Standard deviation CV = . 100% Mean Click the icon to view the data sets.

The mean age is 28.6 years, with a standard deviation of 3.4 years. The winner in one recent year was 20 years old. (a) Transform the age to a z-score. (b) Interpret the results. (c) Determine whether the age is unusual.The ages of the winners of a cycling tournament are approximately bellshaped. The mean age is 28.3 years, with a standard deviation of 3.? years.
