The accuracy of any particular approximation is not known precisely, though probabilistic statements concerning the accuracy of such numbers as found over many experiments can be constructed. Assume that the population is infinitely large, so an infinite number of samples can be drawn from the population. In the past, basketball statistics were a luxury available only to professional and major college teams. For the average coach, statistics were a nightmare, requiring great amounts of time and effort in acquiring and training statisticians and then manually compiling the various stats and percentages.
