The expected rate of deviation in a population primarily indicates the anticipated failure rate of controls. This concept is crucial in auditing, as it helps auditors assess how often the internal controls are expected to fail or not function as intended. By estimating this rate, auditors can determine the level of reliance they can place on these controls when conducting their assessments.

When the expected rate of deviation is considered high, it suggests that there may be significant weaknesses in a company's internal controls. Therefore, auditors may decide to perform additional testing to confirm the effectiveness of these controls or potentially reassess their risk assessment regarding the entity being audited.

The anticipated failure rate of controls plays a vital role in sampling techniques, as it informs auditors about how many errors they might expect to find in a given sample. This, in turn, affects how large a sample size they might need to ensure that their findings align with the overall population's control effectiveness. Understanding this rate is essential for making informed decisions about further audit procedures and the overall assessment of the reliability of the financial statements.
