Chapter 9: Audit Sampling: An Application to Substantive Tests of Account Balances Flashcards
Allowance for sampling risk
The uncertainty that results from sampling. the difference between the expected mean of the population and the tolerable deviation or misstatement
Audit sampling
The selection and evaluation of less than 100 percent of the population of audit relevance such that the auditor expects the items selected to be representative of the population and, thus, likely to provide a reasonable basis for conclusions about the population
Classical variables sampling
The use of normal distribution theory to estimate the dollar amount of misstatement for a class of transactions or an account balance
Confidence bound
A measure of sampling risk added and subtracted to the projected misstatement to form a confidence interval
Expected misstatement
The amount of misstatement that the auditor believes exists in the population
Factual misstatements
These are misstatements about which there is no doubt.
Example: an auditor may test a sales invoice and determine that the prices applied to the products ordered are incorrect. Once the products are correctly priced, the amount of misstatement is known. In such cases, the auditor knows the exact mount of the misstatement
Monetary-unit sampling (MUS)
Attribute-sampling techniques used to estimate the dollar amount of misstatement for a class of transactions or an account balance
Nonsampling risk
The risk that the auditor reaches an erroneous conclusion for any reason not related to sampling risk (e.g., judgement error, inappropriate procedures, failing to detect a misstatement when applying an audit procedure)
Nonstatistical sampling
Audit sampling that relies on the auditor’s judgment to determine the sample size, select the sample, and/or evaluate the results for the purpose of reaching a conclusion about the population
Projected misstatement
These are the auditor’s best estimate of misstatements in populations, involving the projection of misstatements identified in an audit sample to the entire population from which the sample was drawn.
Risk of incorrect acceptance
The risk that the sample supports the conclusion that the recorded account balance is not materially misstated when it is materially misstated
Risk of incorrect rejection
The risk that the sample supports the conclusions that the recorded account balance is materially misstated when it is not materially misstated
Sampling risk
The possibility that the sample drawn is not representative of the population and that, as a result, the auditor reaches an incorrect conclusion about the account balance or class of transactions based on the sample
Sampling unit
The individual item constituting a population being sampled
Statistical sampling
Sampling that uses the laws of probability to select and evaluate the results of an audit sample, thereby permitting the auditor to quantify the sampling risk for the purpose of reaching a conclusion about the population
