The difference between Geometric mean and Quadratic mean

When used as nouns, geometric mean means a measure of central tendency of a set of n values computed by extracting the nth root of the product of the values, whereas quadratic mean means a type of average, calculated as the square root of the mean of the squares, ie. q = \sqrt { x_1^2 + x_2^2 + ... + x_n^2 \over n }.


check bellow for the other definitions of Geometric mean and Quadratic mean

  1. Geometric mean as a noun (mathematics):

    A measure of central tendency of a set of n values computed by extracting the nth root of the product of the values.

    Examples:

    "The geometric mean of 2, 4 and 1 is <math>\sqrt[3]{2 \times 4 \times 1}</math> = 2"

  1. Quadratic mean as a noun (mathematics):

    A type of average, calculated as the square root of the mean of the squares, ie. Q = \sqrt { x_1^2 + x_2^2 + ... + x_n^2 \over n }.
