# PERCENTRANK.INC function

Returns the rank of a value in a data set as a percentage (0..1, inclusive) of the data set.

This function can be used to evaluate the relative standing of a value within a data set. For example, you can use PERCENTRANK.INC to evaluate the standing of an aptitude test score among all scores for the test.

## Syntax

PERCENTRANK.INC(array,x,[significance])

The PERCENTRANK.INC function syntax has the following arguments:

• Array     Required. The array or range of data with numeric values that defines relative standing.

• X     Required. The value for which you want to know the rank.

• Significance     Optional. A value that identifies the number of significant digits for the returned percentage value. If omitted, PERCENTRANK.INC uses three digits (0.xxx).

## Remarks

• If array is empty, PERCENTRANK.INC returns the #NUM! error value.

• If significance < 1, PERCENTRANK.INC returns the #NUM! error value.

• If x does not match one of the values in array, PERCENTRANK.INC interpolates to return the correct percentage rank.
