The use of statistical sampling procedures helps minimize:
A. sampling risk.
B. detection risk.
C. inherent risk.
D. control risk.
Answer / guest
Answer: B
Detection risk is the risk that the IS auditor uses an
inadequate test procedure and concludes that material errors
do not exist, when in fact they do. Using statistical
sampling, an IS auditor can quantify how closely the sample
should represent the population and quantify the probability
of error. Sampling risk is the risk that incorrect
assumptions will be made about the characteristics of a
population from which a sample is selected. Assuming there
are no related compensating controls, inherent risk is the
risk that an error exists, which could be material or
significant when combined with other errors found during the
audit. Statistical sampling will not minimize this. Control
risk is the risk that a material error exists, which will
not be prevented or detected on a timely basis by the system
of internal controls. This cannot be minimized using
statistical sampling.
