Chapter 8 Flashcards
The selection and evaluation of less than 100 percent of the items in a population of audit relevance selected in such a way that the auditor expects the sample top be representative of the population and thus likely to provide a reasonable basis for conclusions about the population
Audit Sampling
Two forms of Audit Sampling
Statistical and Non-Statistical
Research suggest what type of Audit Sampling is more common?
Non-Statistical
AU 530.14 states what?
The amount of Statistical and Non-Statistical sampling should be about the same size.
The possibility that the sample drawn is not representative of the population and that, as a result, the auditor will reach an incorrect conclusion.
Sampling Risk
A sample where the the evaluatoin of that smaple results leads to the same conclusion that would be drawn if the same procedures where applied to the entire population.
Representative Sample
Two Types of Decision Errors with Sampling
- Risk of incorrect rejection (Type 1)
2. Risk of incorrect acceptance (Type 2)
Type 1 errors relate to what quality of the audit?
Efficenciy
Type 2 errors relate to what quality of the audit?
Effectiveness
Deciding that the population tested is not acceptable when in reality it is, is what type of error?
Type 1
Deciding that the population tested is acceptable when in reality it is not, is what type of error?
Type 2
Nonsampling and Sampling risk make up what?
Detection Risk
Nonsampling Risk is what?
The auditor reaches an erroneous conclusion for any other reason than sampling risk.
What can limit Nonsampling Risk
- Training
- Planning
- Supervision
What is the complement to Sampling Risk?
Confidence Level
