## 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

How to calculate relative standard deviation

**First, determine the standard deviation**Calculate the standard deviation of the data set.

**Next determine the mean of the data set**The calculator will use absolute value of this mean for the calculation.

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