HARMEAN(n1,n2)


  • and are the positive real numbers.

Description

  • This function gives the Harmonic Mean of a given set of numbers.
  • Harmonic mean is used to calculate the average of a set of numbers.
  • The Harmonic mean is always the lowest mean.
  • Normally Harmonic mean < geometric mean < Arithmetic mean.
  • Harmonic mean is defined as the reciprocal of the arithmetic mean by the reciprocals of a specified set of numbers.
  • The harmonic mean of a positive real numbers is defined by :

ie

.
  • In HARMEAN(n1,n2,...) n1,n2.. are the positive real numbers, and here n1 is required.n2,n3..., are optional.
  • Also arguments can be numbers,names, arrays or references that contain numbers.
  • We can give logical values and text representations of numbers directly. Suppose the arguments contains any text, logical values or empty cells like that values are ignored.
  • This will give the result as error when 1.the arguments with the error values or the referred text couldn't translated in to numbers.

2.Also any data point<=0.

Examples

  1. HARMEAN(1,2,3,4,5)=2.18978102189781
  2. HARMEAN(20,25,32,41)=27.4649361523969
  3. HARMEAN(0.25,5.4,3.7,10.1,15.2)=1.0821913906985883
  4. HARMEAN(3,5,0,2)=NAN
  5. HARMEAN(1,-2,4)=NAN
