This method provides each unit with an equal probability of selection, supporting strong statistical inference when evaluating monetary misstatements. The auditor determines the population, sampling unit, and frame, ensuring that the list from which the sample is drawn matches the population definition.
Digital Audit Sampling Techniques: Enhancing Accuracy and Efficiency
Systematic Selection Systematic selection calculates a fixed interval by dividing the population size by the desired sample size, then selecting items at regular intervals after a random start. While straightforward and easy to implement, block selection often delivers weaker statistical properties because items within a block may share similar characteristics.
Each monetary unit in the population stands in as a sampling unit, so a $10,000 invoice has ten times the chance of selection as a $1,000 invoice. Key parameters like tolerable misstatement, expected misstatement, and risk of incorrect acceptance are established, directly influencing sample size and evaluation thresholds.

Auditors typically reserve block selection for non-statistical procedures or when combined with other methods to offset its limitations. PPS sampling is popular for tests of details of balances because it naturally directs attention to high-value items that drive financial statement misstatements.
