Expert Solution
Step 1
  • Coefficient of Variation : 

The coefficient of variation (relative standard deviation) is a statistical measure of the dispersion of data points around the mean. The metric is commonly used to compare the data dispersion between distinct series of data. Unlike the standard deviation that must always be considered in the context of the mean of the data, the coefficient of variation provides a relatively simple and quick tool to compare different data series.   

Mathematically, the standard formula for the coefficient of variation is expressed in the following way : 

Coefficient of Variation Formula

Where:

  • σ – the standard deviation
  • μ – the mean
