However, it is not always possible due to bad luck or pure errors in judgment. Tolerable misstatement represents the maximum misstatement that could occur before the population would be considered materially misstated. This rate is based on the tolerable misstatement relative to the number and dollar size of traansactions included in the population.
This rate is directly related to sample size. Exceptions or misstatements that are intentional will normally affect the audit tests performed even when the quantitative analysis supports effective controls or no material misstatement.
The risk of assessing control risk too low represents the risk that an audit sample supports the conclusion that the design and operation of an internal control is effective when in fact it is not.
The lower the required tolerable misstatement relative to the number and dollar size of transactions the lower the needed tolerable deviation rate. It is different from other sampling approaches used by auditors in that each dollar in the population is treated as a separate sampling unit instead of each customer, invoice, check, vendor, etc.
This estimate is based on prior Audit sampling with the client and is normally expected to be zero when PPS is used. This rate is inversely related to sample Audit sampling.
If the allowance for sampling risk is large and positive the auditor would most likely conclude that the design and operation of an internal control is effective.
Sample size for attribute sampling can be determined by reference to attribute sampling tables. The adjusted upper limit on misstatement is calculated by subtracting from the unadjusted upper limit on misstatement the estimated dollar understatement in the population.
Risk of incorrect acceptance represents the risk that the auditor concludes that a material misstatement does not exist when in fact a material misstatement does exist. The estimated dollar overstatement is calculated based on the number of observed overstated dollars.
This estimate is normally based on prior experience with the client. Random Sampling involves selecting items from the population so that each item has an equal chance of being selected. 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. Sample results are evaluated by comparing the computed maximum population deviation rate to the tolerable deviation rate.
The second step is to calculate an unadjusted upper and lower limit on misstatement using the PPS table. Nevertheless both probability and non-probability selection methods are considered acceptable and used in practice.
A lower risk of incorrect acceptance is used when more costly or difficult evidence will be required if expanded testing is needed.Audit Sampling speciﬁc objective.
For example, conﬁrming recorded receivables cannot be re-lied on to reveal unrecorded receivables. MANUAL AUDIT SAMPLING Sampling is the application of an audit procedure to less than % of the items within an account balance or class of transactions for the purpose of evaluating some characteristic of all the items within the balance or.
Audit sampling is the application of an audit procedure to less than percent of the items within an account balance or class of transactions for the purpose of evaluating some characteristic of the balance or class.
Definition of audit sampling: The process of using auditing procedures to under percent of various items in a company's account balance such that each unit may have an equal opportunity of being selected.
Audit sampling can be defined as the process of applying auditing procedures to under % of different items in an organization’s account balance in a way that every single unit might have an equal probability of being selected. Audit sampling is also widely known to reduce the risk of ‘over-auditing’ in certain areas, and enables a much more efficient review of the working papers at the review stage of the audit.
In devising their samples, auditors must ensure that the sample selected is representative of the population.Download
