5.2: Mean or Expected Value and Standard Deviation
P(x = 5) = 1 50. (5)( 1 50) = 5 50. (5 – 2.1) 2 ⋅ 0.02 = 0.1682. Add the values in the third column of the table to find the expected value of X: μ = Expected Value = 105 50 = 2.1. Use μ to complete the table. The fourth column of this table will provide the values you need to calculate the standard deviation.

Mean Deviation — from Wolfram MathWorld
7 juin 2024The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data’s mean. For a sample size N, the mean deviation is defined by MD=1/Nsum_(i=1)^N|x_i-x^_|, (1) where x^_ is the mean of the distribution. The mean deviation of a list of numbers is implemented in the Wolfram Language as MeanDeviation[data].
