Hypergeometric sampling

The following conditions characterize the hypergeometric distribution: • The result of each draw (the elements of the population being sampled) can be classified into one of two mutually exclusive categories (e.g. Pass/Fail or Employed/Unemployed). • The probability of a success changes on each draw, as each draw decreases the population (sampling without replacement from a finite population). WebThis utility calculates the required sample size and cut-point for testing to demonstrate population freedom from disease using imperfect tests and allowing for small populations. This utility uses the methods described by: Cameron and Baldock (1998): A new probability formula for surveys to substantiate freedom from disease.
