2b shows the empirical inverse CDF for sepal length. Because n = 150 is even, the sample median is the value at positions n2 = 75 and n + 1 = 76 in sorted order. 8. 1. 1. Sample mean for sepal length. Multiple occurrences of the same value are shown stacked. 2. Empirical CF and inverse CDF: sepal length. 2 Measures of Dispersion The measures of dispersion give an indication about the spread or variation in the values of a random variable. Range The value range or simply range of a random variable X is the difference between the maximum and minimum values of X, given as r = max{X} − min{X} The (value) range of X is a population parameter, not to be confused with the range of the function X, which is the set of all the values X can assume.
