Geometric standard deviation ÷
WebHow is the SD calculated? 1.Compute the square of the difference between each value and the sample mean. 2.Add those values up. 3.Divide the sum by N-1. This is called the variance. 4.Take the square root to obtain the Standard Deviation. WebThe geometric mean is defined as: x 1 ⋅ x 2 ⋅ x 3 … ⋅ x n n. The geometric mean and geometric standard deviation are restricted to positive inputs (because otherwise the answer can have an imaginary component). Hence if any argument is negative, the result will be NA. If any argument is zero, then the geometric mean is zero.
