HARMEAN function

PRO

The HARMEAN function in Jspreadsheet Formulas Pro is a mathematical tool that calculates the harmonic mean of a specified set of numbers. It is particularly useful when dealing with rates or ratios. You input your data set into the HARMEAN function, and it will return the harmonic mean of those numbers, which is a type of average. This function is beneficial for specific statistical analyses in your data management tasks.

Documentation

Returns the harmonic mean of a data set.

Syntax

HARMEAN(number1, [number2],...)

Parameter	Description
`number1`	The first number or range of numbers for which to calculate the harmonic mean.
`numberN`	Optional. Additional numbers or ranges of numbers for which to calculate the harmonic mean.

Behavior

The HARMEAN function calculates the harmonic mean of a dataset. This function ignores empty cells, text, and boolean values. However, it does include zero values, which can lead to a #DIV/0! error if the dataset contains a zero. Furthermore, if the argument to the function is a logical value or a text representation of a number, the function converts it into a number. If the argument is an array or reference, only numbers in that array or reference are counted. The HARMEAN function also returns an error if any value in the dataset is less than zero.

Common Errors

Error	Description
`#DIV/0!`	This error occurs if the dataset contains a zero.
`#VALUE!`	This error occurs if one or more arguments are non-numeric and cannot be converted.
`#NUM!`	Returned if any value is zero or negative.

Best practices

Always ensure that your dataset does not contain any zero or negative values to avoid errors.

Use the HARMEAN function when dealing with rates. It is more accurate as it gives equal weight to each data point.

Be careful when including cell references or ranges as arguments. The HARMEAN function only includes numbers in its calculation.

Ensure that you input a minimum of 1 argument to avoid the #NUM! error.

Usage

A few examples using the HARMEAN function.

// Example 1: Simple set of numbers
HARMEAN(5, 10, 20)
// Result: 8.571428571

// Example 2: Using a cell range
HARMEAN(A1:A5)

// Example 3: Combining ranges and individual numbers
HARMEAN(A1:A3, 15, 25)

// Example 4: Avoiding zeros and negatives
// Dataset: A1:A4 contains {4, 8, 16, 32}
HARMEAN(A1:A4)
// Result: 8.0
