意外に知られていないが、相加平均・相乗平均・調和平均等々は、関数f(x)を用いて統一的に記述できる

Table with Japanese labels for additive mean, geometric mean, harmonic mean, and RMS. Formulas include f(x) applied to x values, inverse function with sum of f(x_i) from i=1 to n divided by n, log(x) with root of product x1 to xn, and RMS as square root of average of x squared.
