The sampling method requires the auditor testing of the internal control system and basic tests for financial operations to reach an understanding' studying and evaluating risks and methods of control processes and assertions that support the audit's opinion and convictions in actual results of the tasted samples. Auditors use statistical and unstatistical sampling teqniques (Judicious) in determining the suitable samples size and evaluating results of inspection methods of control and financial operations and the extent of their representation for the community items. Methods of statistical inspection were preferred in practical operations for judicious inspection method because of it's ability for quantitative measurement of risk inspection which the auditor wants to undertake and be in control of evaluating test results of selected samples.
