Returns the harmonic mean of a data set. The harmonic mean is the reciprocal of the arithmetic mean of reciprocals.
Syntax
HARMEAN(number1,number2,...)
Number1,number2, ... are 1 to 30 arguments for which you want to calculate the mean.
Remarks
-
The arguments must be either numbers or column references that contain numbers.
-
If a column reference argument contains text, logical values, or is empty, those values are ignored; however, arguments with the value zero are included.
-
If any data point ≤ 0, HARMEAN returns the #NUM! error value.
-
The harmonic mean is always less than the geometric mean, which is always less than the arithmetic mean.
-
The equation for the harmonic mean is:
