Which of the following describes a requirement for conducting a statistical sample in compliance reviews?

A larger sample size is indeed required when the variation in errors is greater because a more extensive sample helps ensure that the findings are representative of the population being tested. When there is significant variation among the data points, such as inconsistencies or discrepancies in compliance, a larger sample provides a better opportunity to capture the range of variations and obtain reliable results. This approach helps to mitigate the risk of reaching incorrect conclusions based on an unrepresentative sample, allowing for a more accurate assessment of compliance and potential risks.

In compliance reviews, using an appropriate sample size based on the variability of the errors is crucial for statistical validity. If errors are highly variable, relying on a smaller sample could lead to oversight of significant issues or misinterpretation of the data. Thus, choosing a sample size that appropriately reflects the population's variability is essential for effective compliance evaluations.
