Formula:`CV = (standardDeviation / mean) × 100%`

## Introduction to Coefficient of Variation Calculator

The coefficient of variation (CV) is a statistical measure of the dispersion of data points in a data series around the mean. It is commonly used to compare the degree of variation between different datasets, even if their means are drastically different. In this formula, CV represents the coefficient of variation, mean is the average of the data points, and standardDeviation is a measure of the amount of variation or dispersion of a set of values. The result is expressed as a percentage.

## Parameter usage:

• `mean` = mean of the dataset (cannot be zero)
• `standardDeviation` = standard deviation of the dataset

## Example valid values:

• `mean` = 20
• `standardDeviation` = 3

## Output:

• `CV` = Coefficient of Variation as a percentage

## Data validation

The mean should be greater than zero to perform the calculation.

## Summary

This calculator provides the coefficient of variation, a useful statistic for comparing the relative variability between different data series.
