The standard deviation alone does not measure relative variation. For example, a standard deviation of $1 would be considered large if it is describing the variability from store to store in the price of an ice cube tray. On the other hand, a standard deviation of $1 would be considered small if it is describing store-to-store variability in the price of a particular brand of freezer. A quantity designed to give a relative measure of variability is the coefficient of...

The coefficient of variation and the standard deviation are two measures of variability or dispersion among data values. Provide two different sets of ten data points each as examples. Calculate the standard deviation and coefficient of variation for each data set, being sure to attach your Excel file to show your work. Explain which of the two mentioned measures can more accurately specify which of these two data sets has more variability or dispersion in their data values and why.
