Instance Property


The mean value of the distribution (also called the expected value or median).


var mean: Float { get }


Random samplings from the distribution are most likely to result in the mean value, with other values increasingly far from the mean occurring with decreasing probability.

This property is read-only—its value is always the midpoint between the values of the inherited lowestValue and highestValue properties (mean = (highest + lowest) / 2).
