Harmonic means are a type of mean. It is the number of values divided by the reciprocal of the values.[1] If there are numbers
, then the harmonic mean of these numbers are
Out of the geometric mean and arithmetic mean, the harmonic mean is usually the smallest.[2]
Example
[change | change source]Let's find the harmonic mean of 2,4 and 5. There are three numbers so we will be dividing three. The reciprocals of the numbers are ,
and
. If we add the reciprocals we get
. If we divide three by this number, the result is
(approximately 3.157894737)
