      It is often difficult to use our standard deviation formula to compare measurements from different populations. Due to this fact, statisticians produced the . coefficient of variation. The coefficient of variation expresses the standard deviation as a percentage of what is being measured relative to the sample or population mean.

      We have already discussed how a probability distribution can be thought of as a relative-frequency distribution. It has a mean and a standard deviation. If we are referring to the probability distribution of a population, then we use the Greek letter μ for the mean and σ for the standard deviation.

      Average Deviation = (Sum of all Deviations)/(# of Measurements) i.e., dav =(di/n where, n is a number of data % Relative Average Deviation = dav/xav x 100. Standard Deviation = [(Sum of all deviations squared/ (# of measurements – 1)]1/2 . dst = s = [ (((xav - xi(2/(n-1))]1/2 = [((di2/(n-1))]1/2. Variance is a square of a standard deviation:
