WebbProbabilities for a Draw without Replacement Example: Probability to pick a set of n=10 marbles with k=3 red ones (so 7 are not red) in a bag containing an initial total of N=52 marbles with m=20 red ones. Total number of objects N N: Number of object distinct from the others m m: Number of objects picked n n: WebbThis lesson starts with the rationale for using unequal probability sampling in section 3.1. We then discuss in section 3.2 the Hansen-Hurwitz estimator which may be used when the sampling is with replacement. In section 3.3, we introduce the Horvitz-Thompson estimator which can be used when the sampling is with or without replacement.

WebbNotice that the main difference between the two sets of formulas is the extra factor on each when we are sampling without replacement. In each case, the extra factor is some number between 0 and 1, so it makes the standard deviation smaller than it is for sampling with replacement. If we actually do sampling without replacement (as we usually WebbCalculating Conditional Probability without Replacement.
