The reciprocal of the harmonic mean of n numbers is the arithmetic mean of their reciprocals. Harmonic mean of various items of a series is the reciprocal of the arithmetic mean of their reciprocals. 


$Harmonic\ mean = \frac{N}{\frac{1}{X_{1}} + \frac{1}{X_{2}}....\frac{1}{X_{n}}}$

  • X1, X2...Xn refer to the value of various items of the series.
  • N = Total number of items of the series.
The following are the steps used in calculating the harmonic mean.
Step-1: Note down the given values in the problem.
Step-2: Enter all the values in the corresponding tab separated by commas.
Step-3: Get the answer for harmonic mean.
