Web31 jan. 2024 · To calculate the empirical rule: Determine the mean m and standard deviation s of your data. Add and subtract the standard deviation to/from the mean: [m − s, m + s] is the interval that contains around 68% of data. Multiply the standard deviation by 2: the interval [m − 2s, m + 2s] contains around 95% of data. WebGiven 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 -1.0. Two Standard Deviations Below The Mean
