Sampling design


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

Mathematical formulation

, a sampling design is denoted by the function which gives the probability of drawing a sample

An example of a sampling design

During Bernoulli sampling, is given by
where for each element is the probability of being included in the sample and is the total number of elements in the sample and is the total number of elements in the population.
