Inthe first place, the sample considered will necessarily consist of afinite number of trials instead of an infinite number as assumed inthe mathematical theory, and the trials may not be completely inde-pendent or entirely uniform. Secondly, even if the individual samplepossessed the ideal characteristics assumed in the mathematicalformulation, the actual series of samples must be finite and the samplesmay be interdependent and far from uniform.
