• The empirical distribution function (e.d.f.) is an estimator of the true c.d.f. – it can be calculated from the sample data. Example: Suppose heights of adult females have normal distribution with mean 65 inches and standard deviation 2.5 inches. The c.d.f. of this distribution is: • Now suppose we do NOT know the true height distribution.
