ACCA Audit and Assurance (F8) Practice Exam

What is non-sampling risk?

1. Risk associated with sample size limitations

2. Risk of errors due to inappropriate sampling methods

3. Risk of erroneous conclusions due to factors other than sample size

4. Risk associated exclusively with judgement errors

The correct answer is: Risk of erroneous conclusions due to factors other than sample size

Non-sampling risk refers to the potential for incorrect conclusions to be drawn during an audit as a result of errors that are not related to the size of the sample taken. This type of risk can arise from various factors, such as misinterpretation of evidence, inadequate understanding of the client's business operations, or errors in applying audit procedures. Choosing the correct approach to minimizing non-sampling risk involves implementing thorough training for auditors, maintaining clear communication among team members, and ensuring comprehensive documentation of audit findings. By focusing on these areas, auditors can effectively reduce the likelihood of incorrect conclusions stemming from human error or misunderstanding rather than from the sample size itself. In contrast, the other options focus on aspects that are components of sampling risk or are overly narrow in scope. The limitations tied to sample size are relevant but are classified under sampling risk rather than non-sampling risk. Inappropriate sampling methods certainly contribute to the overall quality of audit conclusions, but they are also tied to sampling risk because they involve how the sample is selected rather than the interpretation of the results. Limitations due to judgment errors can exist, but they do not encompass all forms of non-sampling risks, which are broader and include various types of systematic mistakes unrelated to sampling methodology or size.
