What is RAT-STATS used for?

RAT-STATS is a statistical software tool used primarily for estimating sample sizes in audits and evaluations, making it particularly relevant for statistical sampling size estimation. In the context of medical auditing, it assists auditors in determining how many records need to be sampled to achieve a statistically valid result. This is crucial for ensuring that audit findings and conclusions are based on an appropriate sample that can accurately represent a larger population.

By applying proper statistical methods, RAT-STATS aids in the methodology of auditing by ensuring that the sampled data is sufficient to draw reliable conclusions about billing practices, compliance, or other areas of review. This focus on establishing an adequate sample size helps to minimize errors and ensures that the results of the audit are meaningful and actionable. Understanding this function of RAT-STATS is key for auditors in conducting effective assessments and for reinforcing the credibility of their findings.
