SAMPLING WITH REPLACEMENT

Statistics Directorate    
Definition:
When a sampling unit is drawn from a finite population and is returned to that population, after its characteristic(s) have been recorded, before the next unit is drawn, the sampling is said to be “with replacement”. In the contrary case the sampling is “without replacement”.

Context:
A different usage occurs in sample surveys when samples are taken on successive occasions. If the same members are used for successive samples there is said to be no replacement; but if some members are retained and others are replaced by new individuals there is said to be “partial replacement”.
