geometric vs arithmetic define
Geometric mean. In mathematics, the geometric mean is a type of mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).
Arithmetic Mean. Turns out that there's more than one way to calculate the mean of a distribution. The method we probably associate with the average, is also known as the arithmetic mean. The arithmetic mean is calculated by adding up all the numbers in a data set and dividing the result by the total number of data points. Example: Arithmetic mean of 11, 13, 17 and 1,000 = (11 + 13 + 17 + 1,000) / 4 = 260.25. Geometric Mean. There is another way to calculate the mean, known as the geometric mean.
