An Empirical Evaluation of Central Tendency Measures
... calculated for each sample and evaluated based on two criteria. First, average absolute percent errors over the 2,000 samples were calculated. This gauges the accuracy of the central tendency measures in estimating their corresponding population parameters. Second, the standard deviations of 2,000 c ...

The Poisson distribution
... cumulative probability is almost equal to 1. • In applications this means that, if say, the family size follows a Poisson distribution with mean 5, then it is almost certain that every family will have less than 12 members. ...
