  1. The relative standard deviation (RSD) shows the deviation of the usual standard deviation when the mean of the data set is compared. \(RSD=(\frac{Standard\,deviation}{Mean})(100)\).
  2. The % of the relative error (RE %) is a form to express the accuracy of a determination respect to a central tendency \(RE=(\frac{Observed\,concentration-Nominal\,concentration}{Nominal\,Concentration})(100)\) n = 3.
