How does data aggregation assist in data analysis?

Data aggregation is a crucial process in data analysis that combines information from various sources and summarizes it to provide a clearer and more comprehensive overview. When data is aggregated, individual data points are grouped together, which helps uncover patterns and trends that may not be apparent when looking at raw data alone.

This comprehensive overview allows analysts to see connections and relationships within the data that inform decision-making processes. By condensing large amounts of data into understandable summaries, data aggregation not only simplifies analysis but also enhances the ability to derive meaningful insights quickly.

In contrast, while isolating data might be beneficial in some contexts, it doesn't facilitate the broad view necessary for in-depth analysis. Reducing data volume can be useful but is not the primary goal of aggregation; instead, the focus is on meaningful summarization. Lastly, creating visual representations, while valuable for interpretation, is a separate analytical step that typically follows the aggregation process itself.
