central tendency (centrality) 

The tendency of quantitative data to cluster around some central value. The central value is commonly estimated by the mean, median, or mode, whereas the closeness with which the values surround the central value is commonly quantified using the standard deviation or variance. The phrase ‘central tendency’ was first used in the late 1920s.
