Parameter

A parameter is a measurable property or characteristic used to describe a system, process, or object. In data analysis and statistics, it refers to a value that summarizes a whole population, such as the average age or total income of all people in a country. Parameters are essential for understanding and modeling the behavior of complex systems, as they help identify and quantify key features that influence outcomes. Think of parameters as the fundamental numbers that define how something works or behaves at a large scale.
