Which data type helps health administrators analyze trends and outcomes across a patient population?

The correct choice is based on the fact that aggregate data refers to data that has been collected and presented in summary form, which allows health administrators to analyze trends and outcomes across a patient population rather than focusing on individual cases. By using aggregate data, administrators can identify patterns, measure performance, and make comparisons across different groups, which is essential for public health analysis and management decision-making.

In contrast, clinical data pertains to specific patient information and is typically more detailed, focusing on individual patients' health information rather than broader trends. Individual data, although similar to clinical data, emphasizes singular cases without providing a comprehensive overview of a population. Longitudinal data tracks the same individuals over time but might not necessarily provide a population-level perspective for trend analysis. Aggregate data specifically offers the aggregated view needed for effective population health management and trend analysis.
