This checklist is designed to guide auditors in determining the appropriate sampling strategy for an audit process, ensuring that the sample selected is representative and supports the audit objectives.
Clearly outline the objectives of the audit to determine what needs to be assessed through sampling.
Determine the complete set of data or transactions that will be subject to the audit.
Choose an appropriate sampling method (random, stratified, systematic, etc.) based on the audit objectives and population characteristics.
Calculate the required sample size based on the desired confidence level, margin of error, and the variability within the population.
Using the chosen sampling method, randomly or systematically select items from the population to be included in the audit.
Record the rationale for the sampling method, size, and selection process to provide transparency and support findings.
Thoroughly review the selected sample items for compliance with audit objectives, ensuring adequate coverage of all relevant aspects.
