* Attribute is the characteristic being tested in the application. ARACR is the risk that the auditor is willing to take of accepting a control as effective or a rate of monetary misstatements as tolerable when the true population exception rate is greater than the tolerable exception rate. TER is the exception rate that the auditor will permit in the population and still be willing to conclude the control is operating effectively and/or the amount of monetary misstatements in the transactions established during the planning is acceptable. EPER is the exception rate that the auditor expects to find in the population before testing begins. Initial sample size is the sample size decided after considering the above factors in planning. * Exception – deviation from the attribute in a sample item. Sample exception rate -- Number of exceptions in the sample divided by the sample size. CUER -- The highest estimated exception rate in the population at a given ARACR. * Objectives might be: Test the operating effectiveness of controls Determine whether the transactions contain monetary misstatements When sampling is used, auditors must carefully define the characteristics being tested and the exception conditions. The population is those items about which the auditor wishes to generalize. The sample must be selected from the entire population as it has been defined. The sampling unit is defined by the auditor based on the definition of the population and objective of the audit test. * TER represents the highest exception rate the auditor will permit in the control being tested and still be willing to conclude the control is operating effectively. For audit sampling in tests of controls and tests of transactions, that risk is called the acceptable risk of assessing control risk too low (ARACR). ARACR measures the risk the auditor is willing to take of accepting a control as effective when the true population exception rate is greater than TER. A combination of
