A parameter is a numerical value that states something about the entire population being studied. For example, we may want to know the mean wingspan of the American bald eagle. This is a parameter because it is describing all of the population. Parameters are difficult if not impossible to obtain exactly.
In computer programming, two notions of parameter are commonly used, and are referred to as parameters and argumentsâor more formally as a formal parameter and an actual parameter. For example, in the definition of a function such as. y = f(x) = x + 2, x is the formal parameter (the parameter) of the defined function.
