Classical Variable Sampling Two Statistical Sampling Approaches A. PPS - probability proportional to size (e.g., DUS, monetary unit sampling, cumulative monetary amount sampling). This approach is based on attribute sampling theory. It was developed for auditors in the last 30 years and is used almost all of the time today. Hypergeometric distribution. B.
