Question: The following times were recorded by the quarter mile and mile

The following times were recorded by the quarter-mile and mile runners of a university track team (times are in minutes).

After viewing this sample of running times, one of the coaches commented that the quarter-milers turned in the more consistent times. Use the standard deviation and the coefficient of variation to summarize the variability in the data. Does the use of the coefficient of variation indicate that the coach’s statement should bequalified?
