## Sample coefficient of variation Solution

STEP 0: Pre-Calculation Summary
Formula Used
Coefficient of variation = Standard Deviation/Mean of data
CV = σ/x
This formula uses 3 Variables
Variables Used
Coefficient of variation - Coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency.
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.
Mean of data - Mean of data is the average of all observations in a data.
STEP 1: Convert Input(s) to Base Unit
Standard Deviation: 1.33 --> No Conversion Required
Mean of data: 20 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CV = σ/x --> 1.33/20
Evaluating ... ...
CV = 0.0665
STEP 3: Convert Result to Output's Unit
0.0665 --> No Conversion Required
0.0665 <-- Coefficient of variation

## What is Coefficient of variation?

In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage, and is defined as the ratio of the standard deviation . The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an assay.
