Question

What is the aggregate of data called?

Answer 1

Explanation:

Aggregate data refers to numerical or non-numerical information that is (1) collected from multiple sources and/or on multiple measures, variables, or individuals and (2) compiled into data summaries or summary reports, typically for the purposes of public reporting or statistical analysis—i.e., examining trends, making comparisons, or revealing information and insights that would not be observable when data elements are viewed in isolation. For example, information about whether individual students graduated from high school can be aggregated—that is, compiled and summarized—into a single graduation rate for a graduating class or school, and annual school graduation rates can then be aggregated into graduation rates for districts, states, and countries.

While most aggregate education data is numerical—e.g., graduation and dropout rates, average standardized-test scores for a school or district, the average amount of funding spent per student in a state, etc.—it’s both possible and common to aggregate non-numeric information. For example, educators, students, and parents in a school district may be surveyed on a topic, and the information and comments from those surveys could then be “aggregated” into a report that shows what the surveyed individuals generally think and feel about the issue. Information collected during polls, interviews, and focus groups can be aggregated in a similar fashion.
