Coefficient of Variation and Standard Deviation

Coefficient of Variation and Standard Deviation are two measures of dispersion or spread among the data values.

Let's say we have two different sets of data.
Explain which of the two mentioned measures can more accurately find which of these two data sets have more spread or variability in their data values.

You can select five values for each of the two data sets and calculate the standard deviation and coefficient of variation for each data set to clarify your explanation.
