**HARMEAN()**

- Parameters are any set of positive real numbers.
- HARMEAN(), returns values along an exponential trend.

## 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 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 Parameters are any positive real numbers, and here First Parameter is required. From the second parameter 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 .

## ZOS

- The syntax is to calculate HARMEAN in ZOS is .
- Parameters are any set of positive real numbers.

- For e.g.,HARMEAN(20..30,11..15,45.1..56.1..0.5)

## Examples

- =HARMEAN(1,2,3,4,5) = 2.18978102189781
- =HARMEAN(20,25,32,41) = 27.4649361523969
- =HARMEAN(0.25,5.4,3.7,10.1,15.2) = 1.0821913906985883
- =HARMEAN(3,5,0,2) = #N/A (NUMBER > 0 REQUIRED)
- =HARMEAN(1,-2,4) = #N/A (NUMBER > 0 REQUIRED)
