Question 13

Which of the following is a characteristic of non-statistical (judgmental) sampling?

Accepted Answer

The auditor uses professional judgment to select sample items. Non-statistical sampling relies on the auditor's judgment and does not use probability theory.

Answer

Answer

The sample size is determined using statistical formulas

Answer

Question 14

During the follow-up phase of an audit, the auditor discovers that a previous finding has not been remediated. What is the auditor's BEST course of action?

Accepted Answer
