Enter the mean and standard deviation of a data set into the calculator to determine the relative standard deviation.

## Relative Standard Deviation Formula

The following equation is used to calculate the relative standard deviation of a given data set.

RSD = SD / |M| *100

• Where RSD is the relative standard deviation (%)
• SD is the standard deviation
• |M| is the absolute value of the mean

## Relative Standard Deviation Definition

A relative standard deviation is defined as the ratio of the standard deviation to the absolute value of the mean of a data set.

## Relative Standard Deviation Example

How to calculate relative standard deviation

1. First, determine the standard deviation

Calculate the standard deviation of the data set.

2. Next determine the mean of the data set

The calculator will use the absolute value of this mean for the calculation.

3. Finally, calculate the relative standard deviation

Enter the information from steps 1 and 2 into the calculator to determine the relative standard deviation.
