how to calculate geometric mean manually. Geometric Mean X 1 X 2 X 3 X n 1n For example lets say that you have the following 5 values. The harmonic mean is a way to calculate the mean or average of a set of numbers.
To calculate the geometric mean values for columns of data. We can calculate the geometric mean based on these R functions as follows. 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.
To calculate the geometric mean values for columns of data.
