Show Suggested Answer Hide Answer
Suggested Answer: C

The auditor used Data Mining.

Data mining involves exploring large datasets to identify patterns, anomalies, or relationships.

ISO/IEC 20546:2019 Clause 3.5 defines data mining as: ''The process of discovering patterns, correlations, anomalies, and associations within large datasets.''

In ISO/IEC 42001:2023, auditors are encouraged in Clause 9.2.2 to use appropriate technological tools to analyze AI system behavior, including using big data technologies for pattern recognition during audits.

I practiced a similar question, and I think data mining is the best fit because it specifically looks for anomalies in data.

I feel like visual analytics could be a possibility too, especially if they were trying to present the anomalies in a clear way.

I'm not entirely sure, but I remember something about predictive analytics being used for forecasting outcomes. Could that apply to loan approvals?

I think the auditor might have used data mining since it focuses on discovering patterns in large datasets, which seems relevant here.
