Introduction to geometric mean
The geometric mean is the root of the power of the continuous product of the variables. The method of finding the geometric mean is called the geometric mean. If the total level and total results are equal to the sum of the product of all stages, all levels, and results, find the general level and general results of each phase and each link. The geometric average method should be used to calculate the geometric mean. Calculate the arithmetic mean. According to the different forms of grip data, it is divided into two forms: simple geometric mean and weighted geometric mean.
