Geometric Mean. The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. First we multiply them: 2 Ã 18 = 36. Then (as there are two numbers) take the square root: â36 = 6.
Etymology: ME, mene, in the middle. occupying a position midway between two extremes of a set of values or data. The arithmetic mean is a value that is derived by dividing the total of a set of values by the number of items in the set.The geometric mean is a value between the first and last of a set of values organized in a geometric progression. Compare median, mode. Statistics.eometric mean. the antilog of the mean of the logarithm of the calculated values, the same as the n th root of the product of the values. It is often a more useful mean for growth curves. harmonic mean. the reciprocal of the arithmetic mean of values converted to their reciprocals (used in dealing with skewed data).
