Normal Curve. Normal Curve, the symmetrical bell-shaped curve of a normal distribution. Many values (numerical quantities) in nature that would seem to vary randomly in fact form a normal distribution. In a normal distribution, the values cluster around an average value and fewer values are found at increasing distances from the average. A graph of the heights of a group of similarly aged people, for example, will tend to form a bell-shaped curve. Microsoft ® Encarta ® 2009. © 1993-2008 Microsoft Corporation. All rights reserved.
