Geometric Mean Formula In Statistics. This can be seen from the formula for the geometric mean. The mean for grouped data is obtained from the following formula. However the actual formula and definition of the geometric mean is that it is the n-th root of the product of n numbers or. X n n 1 3 9 27 81 5 3 3 3 3 3 4 5 3 10 5 3 2 5 5 9 5 5 9.
Geometric Mean n-th root of X1X2Xn. Geometric Mean a1 a2. The geometric mean is a type of average usually used for growth rates like population growth or interest rates. While the arithmetic mean adds items the geometric mean multiplies items. Rn growth rate for year N. A n t i l o g f log x N A n t i l o g o f 11623 5 A n t i l o g o f 23246 21115 The Geometric Mean of.
Based on the above mentioned formula Geometric Mean G.
It is a type of mean that indicates the central tendency of a set of numbers by using the product of their values. Basically we multiply the numbers altogether and take the nth root of the multiplied numbers where n is the total number of data values. Geometric mean for grouped data. The geometric mean of a data set is given by. The geometric mean is used to tackle continuous data series which the arithmetic mean is unable to accurately reflect. Thus geometric mean of given numbers is 9.
