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:
