AICPA Exam CPA-Auditing Topic 1 Question 14 Discussion

Choice 'd' is correct. Variables sampling is used to estimate a numerical measurement of a population, such as the dollar value or the dollar value of errors in the population.

Choice 'a' is incorrect. Discovery sampling is a special case of sampling for 'attributes' (errors) where the auditor's initial estimate of error occurrence is zero or near zero. It does not sample for dollar value.

Choice 'b' is incorrect. The term 'numerical sampling' is not used in statistical sampling and is merely a well-designed distractor.

Choice 'c' is incorrect. Attribute sampling is sampling for errors (or some other attribute). The auditor determines whether the attribute appears or not, but does not try to estimate a numerical measurement of the population.
