WebExample: One Standard Deviation Below The Mean. Given a normal distribution with a mean of M = 100 and a standard deviation of S = 15, we calculate a value of M – S = 100 – 15 = 85 is one standard deviation below the mean. So, a value of 115 is the 84.1 st percentile for this particular normal distribution. This corresponds to a z-score of ...
