WebThe mean defines the average of numbers in the data set. The different types of mean are Arithmetic Mean (AM), Geometric Mean (GM), and Harmonic Mean (HM). In this lesson, let us discuss the definition, formula, properties, and applications of geometric mean and also the relation between AM, GM, and HM with solved examples in the end.

Geometric Mean and Harmonic Mean - maxvalue.com
WebIf G is the geometric mean, H is the harmonic mean, and A is the arithmetic mean, then the relationship between them is given by: \(\begin{array}{l}G = \sqrt{AH}\end{array} \) … In mathematics, the geometric–harmonic mean M(x, y) of two positive real numbers x and y is defined as follows: we form the geometric mean of g0 = x and h0 = y and call it g1, i.e. g1 is the square root of xy. We also form the harmonic mean of x and y and call it h1, i.e. h1 is the reciprocal of the arithmetic mean of the … See more M(x, y) is a number between the geometric and harmonic mean of x and y; in particular it is between x and y. M(x, y) is also homogeneous, i.e. if r > 0, then M(rx, ry) = r M(x, y). If AG(x, y) is the See more • Arithmetic–geometric mean • Arithmetic–harmonic mean • Mean See more We have the following inequality involving the Pythagorean means {H, G, A} and iterated Pythagorean means {HG, HA, GA}: $${\displaystyle \min(x,y)\leq H(x,y)\leq HG(x,y)\leq G(x,y)\leq GA(x,y)\leq A(x,y)\leq \max(x,y)}$$ See more • Weisstein, Eric W.
