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.
Now it is time to analyze this information using the concepts of parameters and statistics. A parameter is the characteristics used to describe a population. For example, Lenae knows one parameter of her population is that they all live in the same town. This is a 100% known parameter of the population. If Lenae was able to see a 100% accurate census in the town, she could probably find parameters such as the number of people in a certain age range in the population. It's hard to have 100% proof for particular characteristics of a population.
