Relative Standard Deviation (RSD) and
Coefficient of Variation (CV)
Frequently standard deviations are given in relative rather
than absolute terms. We calculate the relative standard
deviation by dividing the standard deviation by the mean
value of the data set. The relative standard deviation, RSD, is
sometimes given the symbol sr.
The result is often expressed in 100%. For example,
% 100 %
