# PERCENTRANK

Returns the rank of a value in a data set as a percentage 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 to evaluate the standing of an aptitude test score among all scores for the test.

Syntax

PERCENTRANK(array,x,significance)

Array     is the array or range of data with numeric values that defines relative standing.

X     is the value for which you want to know the rank.

Significance     is an optional value that identifies the number of significant digits for the returned percentage value. If omitted, PERCENTRANK uses three digits (0.xxx).

Remarks

• If array is empty, PERCENTRANK returns the #NUM! error value.
• If significance < 1, PERCENTRANK returns the #NUM! error value.
• If x does not match one of the values in array, PERCENTRANK interpolates to return the correct percentage rank.
