(Type an integer or decimal rounded to three decimal places as needed.)
What is true of the coefficient of variation?
OA. When converting units of measure, the coefficient of variation is unchanged.
OB. The coefficient of variation does not give as accurate a measurement as the standard deviation.
OC. The coefficient of variation is always more meaningful than the standard deviation.
OD. The coefficient of variation is best used when comparing two data sets that use the same units of measure.

have more spread.
(e) In the table below, the data set on the left has the heights of students measured in inches, while the data set on the right has the same students' heights measured in centimeters. For each data
set, determine the mean and the standard deviation. Draw a conclusion about the spread using the standard deviation, then find the coefficient of variation for both data sets.
