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 this use, the word parameter is used to mean the particular value of a parameter, and comes close to meaning a set limit or boundary. For example, a budget can be thought of as a set of parameters that determine a range of activity, much like a set of mathematical parameters that establish the range of effects, or limits, of other variables.
