Monetary-Unit Sampling

Monetary-unit sample selection views the population, not as a population of accounts of different sizes, but as a population of monetary units. The size of the population is taken to be the total number of monetary units in all the accounts and each monetary unit is selected with equal probability i.e., each monetary-unit has an equal chance of selection. Monetary-unit sample selection gives each line item a probability of selection proportional to its stated monetary value. This is the most commonly used statistical method for obtaining samples of line items.
