In the theory of finite population sampling, a sampling design specifies for every possible sample its probability of being drawn.

Mathematically, a sampling design is denoted by the function P(S) which gives the probability of drawing a sample S.

An example of a sampling design

During Bernoulli sampling, P(S) is given by

P(S)=qNsample(S)×(1q)(NpopNsample(S))

where for each element q is the probability of being included in the sample and Nsample(S) is the total number of elements in the sample S and Npop is the total number of elements in the population (before sampling commenced).
