Pronunciation: /ˈsɛn.tər/ Explain

A center is an object that has a symmetrical relationship to a set. There are several different types of sets for which centers are defined:

  • Sets of numbers: The most common centers used for sets of numbers are the mean, median and mode.
  • Datasets (statistics): Besides the centers defined for sets of numbers, there are a number of centers that are important in statistics, including the geometric mean.
  • Geometric objects: Each class of geometric object may have one or more centers defined. The geometric object with the most centers defined may be the triangle: centroid, circumcenter, incenter, center of the nine point circle and many more.
