Editing Mean (section)

===Mean of angles and cyclical quantities===
[[Angle]]s, times of day, and other cyclical quantities require [[modular arithmetic]] to add and otherwise combine numbers. These quantities can be averaged using the [[circular mean]]. In all these situations, it is possible that no mean exists, for example if all points being averaged are equidistant. Consider a [[color wheel]]—there is no mean to the set of all colors. Additionally, there may not be a ''unique'' mean for a set of values: for example, when averaging points on a clock, the mean of the locations of 11:00 and 13:00 is 12:00, but this location is equivalent to that of 00:00.
