Excel Function PERCENTILE

PERCENTILE(array, k)

Returns the number corresponding to a particular percentage from an array of numbers (inclusive).

array	The array of values.
k	The percentile value in the range 0..1 (inclusive).

Remarks

* PERCENTILE.INC was added in Excel 2010 to replace this function.
* If "array" is empty or contains more than 8,191 data points, then #NUM! is returned.
* If "k" < 0, then #NUM! is returned.
* If "k" > 1, then #NUM! is returned.
* If "k" is not numeric, then #VALUE! is returned.
* If "k" is not a multiple of 1/(n - 1), then this function interpolates to determine the value at the kth percentile.
* PERCENTILE.EXC was added in Excel 2010 to handle the percentile value in an exclusive range.
* This is the same as QUARTILE except you are not locked into the fixed percentiles of 0, 25, 50, 75 and 100.
* For an illustrated example refer to the page under Advanced Functions.
* For the Microsoft documentation refer to support.office.com
