8: Sufficient and appropriate evidence Flashcards
What is sampling risk?
The possibility that the auditors’ conclusions, based on a sample, may be different from the conclusion that would be reached if the entire population was tested.
What are 5 sampling methods?
- Random
- Systematic
- Monetary unit
- Haphazard
- Block selection
What kind of sampling is below?
Ensures each item in a population has an equal chance of selection, for example, by using random number generators or tables.
Random
What kind of sampling is below?
This involves having a constant sampling interval, such as every 40th item being selected, the starting point for testing is determined randomly
Systematic
What kind of sampling is below?
This is a type of value-weighted selection in which sample size, selection and
evaluation results in a conclusion in monetary amounts.
Monetary
What kind of sampling is below?
Here the auditor selects the sample without following a structured technique. The auditor must ensure that no conscious bias or predictability arises and this method is not appropriate when using statistical sampling.
Haphazard
What kind of sampling is below?
This involves selection of a block(s) of continuous items from within the population. Block selection cannot ordinarily be used in audit sampling because most populations are structured such that items in a sequence can be expected to have similar characteristics to each other, but different characteristics from items elsewhere in the population.
Block selection
What are the two characteristics of statistical sampling?
i. Random selection of the sample items, and
ii. The use of probability theory to evaluate sample results, including measurement of sampling risk.
What does statistical sampling allow for?
Each sampling unit to stand an equal chance of selection.
If a sampling method does not hold the characteristics below
i. Random selection of the sample items, and
ii. The use of probability theory to evaluate sample results, including measurement of sampling risk.
Then it is what kind of sampling?
Non-statistical sampling
What sampling methods are examples of statistical sampling?
Random sampling
Systematic sampling
Monetary unit sampling
What sampling methods are examples of non-statistical sampling?
Haphazard sampling
Block selection
What kind of source is audit evidence most reliable when obtained from?

Valuation Existence Rights and obligations Completeness Presentation
Describe completeness
– All assets, liabilities and equity interests that should have been recorded have been recorded.
Describe Accuracy
the information processed is correct or appropriate
Describe classification
the transaction has be allocated to the right account description
Describe Cut off
the transaction has been dealt with in the right accounting period
Describe occurance
that the transaction has taken place
Describe valuation
–Assets, liabilities and equity interests are included in the financial statements at appropriate amounts
-and any resulting valuation or allocation adjustments are appropriately recorded.
