Relative Standard Deviation

$RSD = sigma / barx$

$(sigma)"Standard Deviation"$

$(barx)"Mean of the Sample"$

Tags

The Relative Standard Deviation (RSD) for a sample data set calculator computes the relative standard deviation based on the standard deviation and the mean of the sample.

INSTRUCTIONS: Enter the following:

(σ) Standard Deviation
( $barx$ ) Sample Mean

Relative Standard Deviation (RSD): The calculator returns the relative standard deviation

The Math / Science

The RSD serves as a gage for how large is the variance as compared to the size of the sample set. The formula for the relative standard deviation is:

$RSD = σ/barx$

where:

RSD = Relative Standard Deviation
σ = Standard Deviation
$barx$ = Mean of Sample
