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:
Example
Col1 | Col2 | Col3 | Col4 | Col5 | Col6 | Col7 | Formula | Description (Result) |
|---|---|---|---|---|---|---|---|---|
| 4 | 5 | 8 | 7 | 11 | 4 | 3 | =HARMEAN([Col1],[Col2],[Col3],[Col4],[Col5],[Col6],[Col7]) | Harmonic mean of the data (5.028376) |
