different from what it would be if the entire population was tested. Nonsampling risk results from human error. It represents how to calculate allowance for sampling risk the risk that the selected audit procedure is not appropriate for the intended purpose or the evidence from an audit procedure is misinterpreted. Nonsampling risk exists regardless of the number of attribute sampling example items selected from a population for testing. Sampling risk should be considered when an auditor performs an audit procedure on less than one hundred percent of a clearly definable population for the purpose of evaluating the population. There are two aspects to sampling risk when performing tests of controls: The risk of assessing control risk too low represents the risk that an audit sample
Allowance For Sampling Risk Definition
supports the conclusion that the design and operation of an internal control is effective when in fact it is not. The risk of assessing control risk too high represents the risk that an audit sample supports the conclusion that the design and operation of an internal control is not effective when in fact it is effective. Similarly there are two aspects to sampling risk when performing substantive tests: The risk of incorrect acceptance represents the risk that an audit sample supports the conclusion that a material misstatement does not exist when in fact a material misstatement does exist. This risk is similar to the risk of assessing control risk too low. The risk of incorrect rejection represents the risk that an audit sample supports the conclusion that a material misstatement exists when in fact a material misstatement does not exist. This risk is similar to the risk of assessing control risk too high. The risk of assessing control risk too low and the risk of incorrect acceptance are concerned with the effectiveness of audit tests while the risk of assessing control risk too high and the risk of incorrect accep

Attribute Sampling PlansA simple statistical application may dramatically improve the reliability of internal control testing. Dennis Applegate January 01, 2010 https://iaonline.theiia.org/attribute-sampling-plans Comments Views Page Image Page ContentA reliability assessment of the organization's internal control system involves deciding how much evidence to gather. Because an examination of all underlying control data is not always feasible, auditors must often draw samples, audit the items selected, and extrapolate the results to the larger population.Either a statistical or nonstatistical approach to sampling how to is acceptable under The IIA'sInternational Standards for the Professional Practice of Internal Auditingand The American Institute of Certified Public Accountants' (AICPA's) Professional Auditing Standards. The use of statistics, however, will help auditors develop sample plans more efficiently and assess sample results more objectively than nonstatistical methods alone. Even a well-designed nonstatistical sample cannot measure the risk that how to calculate the sample is not representative of the population - a distinct advantage of statistically based sampling plans. Moreover, increased regulatory requirements to provide greater assurance over internal accounting controls and company demands for greater productivity from their audit shops make statistical sampling a necessary part of the internal auditor's tool kit. Fortunately, auditors can use statistical sampling techniques without any detailed knowledge of classical statistical theory and still accomplish their audit objectives.AttributeSamplingAttribute sampling plans represent the most common statistical application used by internal auditors to test the effectiveness of controls and determine the rate of compliance with established criteria. The results of these plans provide a statistical basis for the auditor to conclude whether the controls are functioning as intended, reflecting either control compliance or noncompliance - a binary (yes/no) proposition.In developing an attribute sampling plan, the auditor must first define the audit test objective, population involved, sampling unit, and control items to be tested. For example, if the auditor's objective is to determine the percentage of sales orders lackin
