# Coefficient of Variation

**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,

**is the average of the data points, and**

*mean***is a measure of the amount of variation or dispersion of a set of values. The result is expressed as a percentage.**

*standardDeviation*## 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.
