Central Tendency - The numerical average (e.g. mean, median or mode) of a process distribution. Can also be displayed as the centerline of a process control chart.

An indication of the location or centrality of the data. The most common measures of central tendency are: mean (numerical average), median (the midpoint of an order data set such that half of the data points are above and half are below it) and the mode (the value that occurs most frequently).
