Symmetry

Symmetry may refer to any of the following:

1. With communications, see symmetrical.

2. With aesthetics or patterns, symmetric refers to a quality where an object can be divided into two or more pieces that are identical. For instance, as a test, place a mirror on some arbitrary line on an image. If it looks the same in the mirror as it does when the mirror is removed, you have symmetry. A real-world example of symmetry is the wings of a butterfly.

3. With logic, symmetry describes anything that is the same.

4. With data, symmetry, symmetry data, or symmetric data is a distribution of data where the mean, median, and mode are all equal. If these values are not equal, the data is considered skewed. In a graph, it resembles a bell with the highest point(s) in the center and both sides going down symmetrically. It may also be shaped like a "U," with the lowest point(s) in the center and both sides going up symmetrically.
