Who invented Mean, Median and Mode

Mean

The term is first found in the mid-1690s in the writings of Edmund Halley, and it has been used to summarize observations of a variable since the time of Galileo.

Median

An early use in English of the statistical concept of median was Francis Galtons observation that “the median … is the value which is exceeded by one-half of an infinitely large group, and which the other half falls short of”

Mode

An early use of the statistical concept of the mode was by English mathematician Karl Pearson in 1895 when he stated that “I have found it convenient to use the term mode for the abscissa corresponding to the ordinate of maximum frequency”
