We used. a family, a class room, a school or even a city or a school system. If the 50th item is not in section 4, the auditor would select another random section and continue sampling until the 50 items have been counted. Audit sampling is the application of audit procedures to less than 100% of the total population and all the items in the population have the same chance to be selected.

Disadvantages of Snowball Sampling. Each individual dollar in the population is considered a sampling unit, so that account balances or amounts in the population with a higher value have a proportionally . } Accurate clusters that represent the population being studied will generate accurate results.
