How can statistical sampling benefit audit testing?

Statistical sampling is a crucial technique in audit testing that allows auditors to make valid inferences about the entire population based on a smaller, manageable subset of that population. By selecting a representative sample, auditors can analyze the selected items and then extrapolate the findings to the entire population, which helps in assessing the overall accuracy, compliance, and risk levels associated with the data being audited.

This approach is particularly beneficial in circumstances where examining every single item in a population would be impractical in terms of time and resources. Through the use of statistical methods, auditors can determine the likelihood of occurrence of errors or discrepancies within the whole dataset, thereby supporting more efficient and cost-effective audit practices. Furthermore, this method increases the credibility of the audit by basing conclusions on statistical evidence rather than relying solely on non-quantitative measures.

In contrast, other options may suggest various aspects of the audit process, but they do not capture the primary and significant advantage that statistical sampling provides— the ability to extrapolate results across a population. Thus, this characteristic is essential for auditors looking to derive meaningful insights from their tests while ensuring a sound basis for their conclusions.
