Definitions:

Normal Distribution

A symmetrical, bell-shaped distribution of data in which most of the observations cluster around the central peak and the probabilities for values further away from the mean taper off equally in both directions.

Asymptotic

Referring to a line or curve that approaches a given curve arbitrarily closely, as one or both of the variables go to infinity.

Normal Curve

A symmetrical, bell-shaped curve representing the distribution of a set of data where most measurements are close to the average.

Symmetry

The property of being made up of exactly similar parts facing each other or around an axis; often evaluated in statistical data sets.
