Relative standard deviation

In probability theory and statistics, the relative standard deviation (RSD or %RSD) is the absolute value of the coefficient of variation expressed as a percentage.

It is widely used in analytical chemistry to express the precision of an assay.

(standard deviation of array X) × 100 / (average of array X) = relative standard deviation
