Changed: 1c1

A sample is that part of a population which we actually observe. In normal scientific practice, we demand that it be selected in such a way as to avoid presenting a biased view of the population. If Statistical Inference is to be used, there must be a way of assigning known probabilities of selection to each sample, preferably equal. This latter method is called [Simple Random Sampling]?.
