Which term is defined as a characteristic or constant factor?

• A. Parameter
• B. Paroxysmal
• C. Ongoing
• D. Oral

Answer: (A)

A characteristic or constant factor that defines a system is called a parameter. In statistics and modeling, a parameter describes a population (for example, the population mean or population standard deviation) and is treated as a fixed value that characterizes the whole group, even if we don’t know its exact number. The other terms don’t fit this idea: paroxysmal means occurring in sudden bursts, ongoing means continuing, and oral relates to the mouth or spoken language. These don’t describe a defining, unchanging descriptor of a population, so they aren’t the right fit. Parameter best captures the sense of a stable, specifying factor that defines the system.
