What is aggregation in data analysis?

• A. Information is gathered and expressed in a summary form for analysis.
• B. The process of collecting raw data from sources.
• C. The act of encoding data for security.
• D. The method of running simulations of a system.

Answer: (A)

Aggregation in data analysis is the process of turning many individual data points into a single summarized value or set of values so trends and patterns can be seen more clearly. By computing totals, averages, counts, or other summaries, you create a compact view of the data that’s easier to analyze than the raw details. For example, adding up daily sales to get a monthly total or averaging customer ratings by product category are both forms of aggregation. This description aligns with the idea of gathering information and expressing it in a summary form for analysis. Collecting raw data is data collection, encoding data for security is encryption, and running simulations is modeling or simulation.
