WebTo find the percentile of a specific value in a normal distribution, find the z-score first by using the formula. Z= (x-μ)/σ where μ is the mean and σ is the standard deviation of the data set. Then look up that z-score on a z-score table. The corresponding number in the z-score table is the percentage of data below your value. The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.
