**Coefficient of variation and standard deviation are two measures of dispersion or spread among data values. Provide two different sets of ten data points each as examples. Explain which of the two mentioned measures can more accurately specify which of these two data sets have more spread or variability in their data values. Calculate the standard deviation and coefficient of variation for each data set to clarify your explanation.
Needs to be explained in a paragraph or so, and provide the examples on the EXCEL spreadsheet.
