APT Financial Consultants maximum rate of failure of an internal control that can be accepted in order to place reliance on it (and is therefore likely to be small). Definition of key terms: - Population – is the entire set of data from which the auditors wish to sample in order to reach a conclusion. Attribute estimation is the most common.

Perform the sampling plan. F. III. The higher the sample size the higher the degree of reliance, Other forms of attribute sampling.

Discovery sampling:- Called exploratory sampling is a secreening device for punching out populations which require further investigation”. This “systematic selection of sample items is demonstrated below. determine the sample size: 1. desired allowance for sampling risk>achieved allowance for sampling risk.

APT Financial Consultants Some testing procedures do not involve sampling example: Transaction and balances which, though few in number are of great significance in terms of size: e.g. Or particularly when: recorded amounts are not available for individual sampling units or there are few expected differences between audited and recorded values. Auditors attempt to reduce non-sampling risk to a negligible degree by appropriate planning, direction, supervision and review. 15. rate of deviation) c.

a. In substantive procedures, the tolerable error is the maximum monetary error in an account balance or a class of transactions that auditors would be willing to accept so that when the testing (i.e., performing the audit procedure); and 4.evaluation. acceptable risk of incorrect acceptance (ARIA).

An audit population consists of all the items constituting an account balance or class of transactions.

Note the ‘inverse’ nature of the relationship between R-factors and risk and that a confidence level is the mathematical complement of risk. Accounting Dictionary A | B | C | D | E | F | G | H | I | J | K | L | M | N | O ii. Sample size 11.

risk of incorrect acceptance of an account balance (effectiveness) Audit may be in jeporady due to the fact that substantive tests are not expanded to search for the The ratio is then multiplied by the recorded account balance, yielding an estimated audited value, and the achieved allowance for sampling risk is calculated. 3. rate of deviation) Lower tolerable error (ie. expected population deviation rate This rate will be less than the tolerable rate or there is no need to test.

When auditors use this method, care needs to be taken to guard against making a selection that is biased, for example, towards items which are easily located, as they may not Tolerable error Larger measure of tolerable error Smaller measure of tolerable error d. This may result in: (a) ‘The risk of incorrect rejection’ (also called Alpha risk) which arises when the sample indicates a higher level of errors than is actually the case. Such items might imply some characteristic of the remaining portion of the population but would not necessarily be the basis for a valid conclusion about the remaining portion of the population.

Name* Description Visibility Others can see my Clipboard Cancel Save AUDIT SAMPLING IN TESTS OF CONTROLS I. Number of items in population Virtually no effect on sample size unless population is small (1) A high preliminary assessment of control risk may result in a decision not to perform is working to precision of 5%. Size of the firm’s transactions Produce high level of assurance in respect of completeness.

Audit sampling can be used as part of a test of control or as part of a substantive procedure. 4. In designing the sample, auditors define those conditions that constitute an error by reference to the audit objectives. Other techniques are Sequential and Discovery. Evaluation of sample results 26.

Related Book Auditing For Dummies By Maire Loughran Auditors choose from several types of sampling when performing an audit. If balances larger than the sampling internal are present, the size of the sample actually selected will be less than computed. The auditor calculates no estimate of the maximum population deviation rate. precision interval (estimated population value +/- the acheived allowance for sampling risk) should include the recorded population value.

If the maximum population deviation rate is less than the tolerable rate, you would accept the control attribute as being effective. Determine the method of sample selection. Conversely, it is less likely in the absence of fraud, where the various misstatements are more likely to be randomly positive or negative, and so will approximately cancel each other out. The expected error rate is 5 percent.

STEPS: (1) Calculate the most likely error – sort the errors into over and under statements. desired allowance for sampling risk (DASR).
