2. Arithmetic mean - Wikipedia

   en.wikipedia.org/wiki/Arithmetic_mean

   The arithmetic mean can be similarly defined for vectors in multiple dimensions, not only scalar values; this is often referred to as a centroid. More generally, because the arithmetic mean is a convex combination (meaning its coefficients sum to ), it can be defined on a convex space, not only a vector space.

7. Chisini mean - Wikipedia

   en.wikipedia.org/wiki/Chisini_mean

   The arithmetic, harmonic, geometric, generalised, Heronian and quadratic means are all Chisini means, as are their weighted variants. While Oscar Chisini was arguably the first to deal with "substitution means" in some depth in 1929, [1] the idea of defining a mean as above is quite old, appearing (for example) in early works of Augustus De Morgan.
