WebbEmpirical Rule Formula (68 95 99 Rule) To calculate the data ranges associated with the empirical rule percentages of 68%, 95%, and 99.7%, start by calculating the sample mean (x̅) and standard deviation (s). Then input those values into the formulas below to derive the ranges. Data range. Percentage of data in the range. WebbThe fourth column of this table will provide the values you need to calculate the standard deviation. For each value x, multiply the square of its deviation by its probability. (Each deviation has the format x – μ). Add the values in the fourth column of the table: 0.1764 + 0.2662 + 0.0046 + 0.1458 + 0.2888 + 0.1682 = 1.05
