What is the primary purpose of summarizing data in reports?

Summarizing data in reports primarily serves to enhance data visibility through grouping and subtotals. This approach allows users to easily interpret large sets of data by condensing information into manageable segments. By organizing data into categories, users can quickly grasp key insights and trends, making it easier to analyze performance or identify important metrics.

Grouping data and adding subtotals provide a clearer overview, helping stakeholders focus on broader patterns rather than being overwhelmed by granular details. This method is particularly effective in financial reports, sales analysis, and performance metrics where understanding aggregate results is essential for informed decision-making. Overall, effective summarization of data not only improves readability but also facilitates strategic analysis and reporting.
