Relative Standard Deviation Calculator

The relative standard deviation of a set of numbers is a special form of the standard deviation. It is calculated as:
Relative standard deviation: 100 * (s / x)
where s is the sample standard deviation and x is the sample mean.
The relative standard deviation is useful because it tells you whether the sample standard deviation is small or large relative to the sample mean.
To find the relative standard deviation for a set of values, simply enter the comma-separated values in the box below and then click the “Calculate” button.

Relative standard deviation = 42.00%


Explanation

Sample standard deviation (s) = 12.81075

Sample mean = 30.50000

Relative standard deviation = 12.81075 / 30.50000 = 42.00%
