Classification is a data analytics technique used to assign data elements to defined categories or groups based on shared characteristics or patterns. It can help identify transaction types, customer groups, risk categories, behavioral patterns, or exception classes. Stratification divides numeric values into ranges or bands, often to identify high-value items or distribution patterns. Joining different data sources combines records from separate tables or files, such as vendors and employees. Duplicate testing identifies repeated or potentially duplicate records. Internal auditors may use classification to analyze populations, focus risk assessment, detect unusual groups, or support predictive modeling. Because the question asks about identifying patterns among groups of data elements, Option D is correct.
