Test 2 In-Class Flashcards
Sampling Risk:
Type 1 Errors
Risk of incorrect Rejection:
Audit EFFICIENCY is reduced
Auditor erroneously thinks they found a problem
Sampling Risk:
Type 2 Errors
Risk of Incorrect Acceptance:
Audit EFFECTIVENESS is reduced
-Auditor erroneously thinks no problems exist
Based on prior history, you believe the control works 98% of the time. You design a statistical sample of 132 items (see Table 8-6) and find 5 deviations. This gives you a 3% allowance for sampling risk (5% tolerable deviation rate less 2% expected deviation rate).
Expected deviation rate: 2.0%
Sample size: 132
Sample deviation rate (5/132): 3.8%
Allowance for sampling risk: 3.0%
Upper Deviation Rate
= Sample deviation rate + Allowance for sampling risk(tol dev rate - expected dev rate)
If UDR > TDR
we cannot conclude, with XX% confidence that the actual deviation rate for the population is less than the amount that we can tolerate. Thus, we are unable to rely on the control to the level that was originally planned (i.e. raise CR) and would need to increase substantive testing (i.e. lower DR).

Sampling Risk
The risk that the sample drawn does not represent the population. Risk that the auditor’s conclusion based on a sample may be different from the conclusion that would have been reached had the whole population been tested. Can be reduced by ^ sample size and by using a stat unbiased method to choose sample
Non-Sampling Risk
Risk that the sample isn’t representative of pop due to mistakes. Two things that cause it:
1 - Failure to recognize exceptions or errors.
2 - Inappropriate or ineffective audit procedures.
