Historical Context
The practice of auditing has roots tracing back to ancient civilizations. In Ancient Egypt and Mesopotamia, auditors were employed to oversee the storage and distribution of goods, ensuring that records were kept accurately. The term “auditor” itself comes from the Latin word “auditor,” meaning a listener, as early audits involved listening to the oral reporting of financial matters.
Types of Auditors
Auditors can be categorized based on their functions and the nature of their work:
- External Auditors: Typically work for external audit firms and are appointed to audit the financial statements of an organization. They provide an independent opinion on whether the financial statements reflect a true and fair view of the company’s financial position.
- Internal Auditors: Employees of the organization they audit. Their role is to assess the effectiveness of internal controls, risk management, and governance processes.
- Government Auditors: Work for government agencies and focus on auditing government departments and entities to ensure the proper use of public funds.
- Forensic Auditors: Specialize in investigating financial crimes such as fraud and embezzlement.
- Information Technology Auditors: Focus on the controls within an organization’s IT systems to ensure data integrity and security.

In audit sampling, the auditor might use statistical formulas to determine sample sizes. One common model is the attribute sampling formula used to estimate the rate of occurrence of a specific attribute:
where:
- \( n \) = Sample size
- \( Z \) = Z-value (from standard normal distribution)
- \( p \) = Estimated proportion of occurrence
- \( E \) = Acceptable margin of error
