M ˇ i 1 N T N 0 1 x i N T N 0 1 N T N 0 N T where m ˇ is harmonic mean x i is a nonzero value of the data vector N T is the total sample size N 0 is the number of zero values. If all values in a nonempty dataset are equal the three means are always equal to one another. One application is to calculate the average purchase cost of shares purchased over time.
It is calculated by dividing the number of observations by the sum of reciprocal of the observation.
