Central Tendency

A statistical reference to the central area of a distribution for a continuous (a.k.a. variable or numerical) value.  It generally describes the "central" area where most data points "tend" to fall in the distribution. The primary measurements for it are the mean (a.k.a. average), the median (50th percentile), and the mode.
