As statistical terms I think they were created before even I was born. But my feeling is that with the central limit theorem in some form going back a longer time that central tendency may have first been used to describe the tendency for the sample mean to move toward the population mean of a normal distribution. | |

Perhaps the vague notion of the "middle" of a distribution inspired the specific concepts mean, median, mode, & the rest; & then "central tendency" seemed a more dignified word for whatever they might loosely be said to have in common. By the way the median of your example distribution is considered non-unique, like the mode - see Conditions for uniqueness of the median. | |
