WebbStandardizing places a standard deviation in the denominator. If the standard deviation is known, it behaves as a constant and the normal distribution remains. If the standard deviation is estimated from the sample, it follows a probability distribution and the ratio of the numerator’s normal distribution to this distribution turns out to be t .) WebbStandard deviation and Coefficient of Variation; Suppose you have four datasets of the same size and the mean is also the same, say, m. In all the cases the sum of the observations will be the same. Here, the measure of central tendency is not giving a clear and complete idea about the distribution for the four given sets.
