The online Relative Standard Deviation Calculator is used to calculate the relative standard deviation (RSD) of a set of numbers.
In probability theory and statistics, the relative standard deviation (RSD or %RSD) is the absolute value of the coefficient of variation. It is often expressed as a percentage. It is useful for comparing the uncertainty between different measurements of varying absolute magnitude.
The following is the relative standard deviation calculation formula:
s = sample standard deviation
RSD = relative standard deviation
x1, ..., xN = the sample data set
x̄ = mean value of the sample data set
N = size of the sample data set
