Properties of Geometric Mean

The main properties of geometric mean are:

  • The geometric mean is less than arithmetic mean, G.M < A.M
  • The product of the items remains unchanged if each item is replaced by the geometric mean.
  • The geometric mean of the ratio of corresponding observations in two series is equal to the ratios their geometric means.
  • The geometric mean of the products of corresponding items in two series is equal to the product of their geometric mean.
