WebbStandard Deviation. A measure of dispersion around the mean. In a normal distribution, 68% of cases fall within one standard deviation of the mean and 95% of cases fall within two standard deviations. For example, if the mean age is 45, with a standard deviation of 10, 95% of the cases would be between 25 and 65 in a normal distribution. WebbAnswer: sk 1 = -0.31. Example 3: If the coefficient of skewness of a distribution is 0.32, the standard deviation is 6.5 and the mean is 29.6 then find the mode of the distribution. Solution: Using the formula for the first coefficient of skewness, the mode can be determined as follows: sk 1 = ¯. ¯. ウトロゲスタン 使用期限
