how to calculate geometric mean cv. Hence the Geomean of 30000 and 33000 is calculated as. Assume a geometric standard deviation of 102 and a geometric mean of 108.

Extract the parameter results from a PKNCAresults and return. Notice that the geometric CV is independent of the geometric mean unlike the arithmetic CV which is dependent on the arithmetic mean and the geometric CV is used in the sample size calculation. Whereas the arithmetic mean is calculated by summing a series of data points and then dividing that sum by the number of data points Equation 1 the geometric mean multipliesa series of data points and then uses the nnumber of data points to find the nth rootof that product Equation 2.
In other words take the average of the logs.
To calculate the geometric mean we take their product instead. You can also use the logarithmic functions on your calculator to solve the geometric mean if you want. To calculate the geometric mean values for columns of data. Check the box to report Geometric means.
