Audit Sampling Flashcards
Attribute Sampling
Primarily used for testing internal controls
Variable Sampling& PPS
Sampling used in Substantive testing of account balances
Attribute sampling deals with
Characteristics (yes, no?)
Variable sampling deals with
Dollar sampling (whats the amount etc?)
Audit Risk when it comes to sampling
1) Uncertainties due to sampling
2) uncertainties due to factors other than sampling
Sampling Risk
The chance the sample is wrong, leading you to the wrong conclusion
A tolerable deviation rate
is a misstatement
Risk of Assessing Control Risk
Inverse relationship
want less risk larger sample
accept more risk smaller sample
Tolerable Deviation Rate
Inverse Relationship
want less deviation = larger sample
accept more deviation = smaller sample
Expected Deviation Rate
Direct Relationship
Expect less deviation = smaller sample
Expect more deviations= larger sample
Population size
No relation
Upper Deviation Rate
Sample Deviation Rate + Allowance for Sampling Risk
Tolerable Misstatement
maximum monetary misstatement in the related account balances or class of transactions that the auditor is willing to accept
Variable Sampling Plans
Mean-per-unit estimation
Ratio Estimation
Difference Estimation
Comparison of Methods
Attribute Sampling Methods
Discovery Sampling
Stop-or-go Sampling
Mean-per-unit Estimation
uses the avg value of the items in the sample to estimate the true population value
Ratio Estimation
uses ratio of the audited (correct) values of items to their book values to project the true population value
Difference Estimation
uses the average difference between the audited (correct) values of items of their book values to project the actual population value.
In a financial statement audit of a nonissuer, a previously communicated significant deficiency that has not been corrected, ordinarily should be communicated again:
In writing, during the current audit.
n determining the number of documents to select for a test to obtain assurance that all sales returns have been properly authorized, an auditor should consider the tolerable rate of deviation from the control activity. The auditor should also consider the:
Likely rate of deviations.
During the planning phase of the audit, the auditor obtains an understanding of the internal control system by considering:
The types of misstatements that may occur.
The risk that misstatements may occur. Factors that influence the design of tests of controls and substantive tests. The assessment of inherent risk. Judgments about materiality. The complexity and sophistication of the entity's operations and systems. The use of manual vs. computerized control procedures.
