59. Sampling can assist the auditor in various ways during the examination of documentary evidence for tests of internal
279.
controls. Using a vouchering and vendor billing application
280.
as an example, assume that you are interested in evaluating
281.
internal controls relative to ordering goods, receiving
282.
goods, and processing vendor invoices. Discuss how attribute sampling might assist you in the following phases
283.
of your tests of controls:
284.
a. Determining the number of vouchers to test;
285.
b. Selecting the vouchers for testing;
286.
c. Evaluating the results of the voucher test;
287.
d. Assessing audit risk associated with the
288.
expenditure cycle.
289.
SOLUTION:
290.
a. In determining the number of vouchers to test, the auditor will need to set a tolerable occurrence rate and an acceptable risk of underassessment.
These parameters, along with an estimated occurrence rate may then be used as inputs to determining sample size.
291.
b. If vouchers are prenumbered, the auditor can elect to use a random selection approach to selecting vouchers test
292.
for predefined attributes.
293.
c. Having examined the sample for the attributes of interest, the auditor can calculate the observed error
294.
rate and the upper occurrence limit.
295.
d. The upper occurrence limit can be compared with the tolerable occurrence rate to support raising or lowering the assessed level of control risk.

a. Based on the pilot sample, calculate the expected occurrence rate and the tolerable occurrence rate for each attribute.
b. In determining sample size, Jones can select an expected occurrence rate ranging from the low for attribute number 2 to the high for attributes 3 and 4.
What impact will a low rate relative to a high rate have on the calculated sample size?
c. What other factors must Jones consider before determining the sample size?
c. Assuming that a sample of 100 payroll summary entries produced the following calculated upper occurrence limits, what impact will these limits have on
Jones substantive audit program?
Attribute 1: 7.0%
Attribute 2: 4.0%
Attribute 3: 12.0%
Attribute 4: 6.0%
SOLUTION:
a. The tolerable occurrence rate is 10% (4/40) for each of the attributes. The expected occurrence rates are:
Attribute No. 1: 2.5%
Attribute No. 2: 0.0%
Attribute No. 3: 5.0%
Attribute No. 4: 5.0%
b. The higher the expected occurrence rate, the larger will be the sample size.
c. Jones must determine the acceptable risk of underassessing control risk.
d. Only attribute 3 produces an unacceptable upper occurrence limit, exceeding the tolerable rate of 10%.
Given incorrect calculation of gross pay, withholdings, and net pay, Jones should plan to focus more heavily on inventory costing, inasmuch as inventory includes both direct and indirect labor components. He should also concentrate on payroll cost included in general and administrative expense, as well as on accrued payroll and payroll taxes payable at year end.
Incorrect calculation of gross pay and withholdings will also impact the calculation of employer’s payroll

tax expense. Therefore, Jones must plan to audit these accounts more intensively than under conditions of strong internal control.

    It is the simplest type of probability sampling, wherein the probability of an element getting selected is directly proportional to its frequency. It is equivalent to say that every element has the same probability of getting chosen if they have the same frequency. For example in a random number generator each element has the same frequency and hence the same probability i.e. f=n/N.…

    Informative post! I agree a quantitative randomized control study is one mean of assessing the effectiveness of anti-depressive medications on anxiety and depression. This study would present statistical data. However, measuring anxiety and depression with numerical alone may be difficult. Performing a mixed study with both quantitative and qualitative methods would allow for more significant data related to measuring and understanding the improvements of depression and anxiety as these are personal experiences. Qualitative data allows for a greater understanding of one’s beliefs and personal experiences while allowing the researcher to participate more fully in a study and strengthens clinical trials (Pathak, Jena & Kalra, 2013).
