The harmonic mean is a type of numerical average.
It is calculated by dividing the number of observations by the reciprocal of each number in the series. (◍•ᴗ•◍)❤
Thus, the harmonic mean is the reciprocal of the arithmetic mean of the reciprocals. The harmonic mean of 1,4, and 4 is: 3 ( 1 1 + 1 4 + 1 4 ) = 3
