When performing an audit, an auditor bases his/her opinion about whether the financial statements are free from material misstatement on a variety of tests on the underlying account balances and classes of transactions. Some balances, such as debt, may be tested 100% but more often, such as is the case with accounts receivable, the auditor will use sampling applications to obtain sufficient evidence to support the opinion and will not test 100% of the population. The auditor will also use sampling when testing control activities to conclude on the effectiveness of the controls. Compliance and accuracy in the accumulation of information is also tested by sampling. This module explores the different sampling applications used in a financial statement/compliance audit.
