Aggregate data refers to data that is combined from multiple individual cases to provide a summarized view. It typically represents a larger dataset where individual variations are grouped together, enabling trends and patterns to be identified. The term "common variable" signifies that the data has a shared characteristic or metric across different cases, allowing for meaningful analysis of the collective results.

The focus of aggregate data is on the overall trends rather than the specifics of each case, which is why it is essential in fields like healthcare and social sciences for understanding population-level insights. For instance, it allows case managers to analyze the effectiveness of interventions across a broader client base rather than just individual instances.

The other options do not accurately describe aggregate data. Choices suggesting data collected from individual cases, data excluding averages, and data lacking statistical significance do not capture the essence of aggregation, which is fundamentally about combining individual data points to draw broader conclusions.
