A5 Becker HW Flashcards
The use of the ratio estimation sampling as compared to other sampling techniques is most effective when:
The calculated audit amounts are approximately proportional to the client’s book amounts.
In statistical sampling methods used in substantive testing, an auditor most likely would stratify a population into meaningful groups if:
The population has highly variable recorded amounts.
Deviations from specific control activities at a given rate:
Ordinarily result in misstatements at a lower rate.
The risk that the assessed level of control risk based on the sample is greater than the true risk based on the actual operating effectiveness of the control.
The risk of assessing control risk too high
The goal is to ensure selection of items for which potential misstatements may individually equal or exceed tolerable misstatement.
Stratification
Sampling method that is designed to estimate overstatement errors. Zero balances, negative balances, and understated balances require special design considerations.
PPS sampling
The risk that the sample supports the conclusion that the recorded account balance is not materially misstated when in fact it is materially misstated (i.e., sample results fail to identify an existing material misstatement).
The risk of incorrect acceptance
When planning a sample for a substantive test of details, an auditor should consider tolerable misstatement for the sample. This consideration should:
Be related to preliminary judgments about materiality levels.
When using classical variables sampling for estimation, an auditor normally evaluates the sampling results by calculating the possible error in either direction. This statistical concept is known as:
Precision
In a probability-proportional-to-size sample with a sampling interval of $5,000, an auditor discovered that a selected account receivable with a recorded amount of $10,000 had an audit amount of $8,000. If this were the only error discovered by the auditor, the projected error of this sample would be:
The actual difference of $2,000 ($10,000-$8,000) is used when the recorded amount is larger than the sample interval.
Includes all aspects of audit risk that are not due to sampling. Examples include:
Non-sampling risk.Examples of nonsampling risk include: the auditor selecting inappropriate auditing procedures, using inappropriate audit evidence, and failure by the auditor to recognize misstatements in documents examined.
The maximum monetary misstatement in an account balance that may exist without causing the financial statements to be materially misstated. It is a planning concept related to the auditor’s preliminary judgments about materiality levels.
Tolerable misstatement
The auditor controls the risk of incorrect acceptance by specifying that risk level for which type of sampling plan.
PPS Sampling
The inputs for PPS are:
Tolerable misstatement, risk of incorrect acceptance, and the recorded amount of the population being sampled.
An auditor may decide to decrease the acceptable level of risk when:
The cost and effort of selecting additional sample items is low.
