Which is a true statement about the computer-assisted audit tool (CAAT)?

Computer-Assisted Audit Tools (CAATs) are a significant advancement over traditional auditing methods primarily because they enable the analysis of entire datasets rather than relying on statistical sampling. This allows auditors to test 100% of a population, such as all customer addresses over a decade, providing a much higher level of assurance. Traditional methods are constrained by time and resources, necessitating the use of smaller, representative samples from which to extrapolate conclusions about the entire population. Option C accurately captures this fundamental difference in scope and capability between the two approaches.

A. This is misleading. While an auditor could use a sample with CAATs, their primary advantage is moving beyond the limitations of sampling inherent in traditional methods.
B. CAATs are analytical tools that operate on a read-only basis to ensure the integrity of the source data. They do not have the functionality to alter records.
D. This statement is false. CAATs are specifically designed to be customized to handle massive data volumes and execute specific, complex audit tests efficiently.
