WebWhen sampling without replacement the probability of being drawn changes based on the results of the preceding draws. Resampling is term used for a set of statistical techniques. With resampling you have an original sample drawn and then to make inferences about the population based on the sample you do addition sampling from the original sample. WebSampling is called with replacement when a unit selected at random from the population is returned to the population and then a second element is selected at random. Whenever a unit is selected, the population contains all the same units, so a unit may be selected more than once. There is no change at all in the size of the population at any stage.
