The term aggregate refers to a collection or gathering of things, often used in the context of data or statistics. In its most basic sense, an aggregate is a sum or total of various elements or values, such as numbers, amounts, or scores. It can also refer to a mass, heap, or accumulation of something, like rocks, sand, or dust. In addition, the word "aggregate" can be used in a more specific context within fields such as economics, where it refers to the total output of goods and services produced within an economy, or in statistics, where it describes the process of combining data from multiple sources into one dataset.
