QUARTILE

QUARTILE(array, quart)

Returns the quartile of a data set (inclusive).

array	The array or cell range of numeric values.
quart	The number to indicate the quartile you want to return: 0 - Minimum Value 1 - First Quartile (25th percentile) 2 - Median Value (50th percentile) 3 - Third Quartile (75th percentile) 4 - Maximum Value

REMARKS

* This function is only available for backwards compatibility and should not be used.
* QUARTILE.INC was added in Excel 2010 to replace this function.
* For an illustrated example refer to the page under Advanced Functions
* The values in the array do not have to be sorted into ascending order.
* If "array" is empty , then #NUM! is returned.
* If "array" contains more than 8,191 data points, then #NUM! is returned.
* If "quart" is not an integer, it is truncated.
* If "quart" < 0, then #NUM! is returned.
* If "quart" > 4, then #NUM! is returned.
* If "quart" = 0, then this is equivalent to the MIN function.
* If "quart" = 1, then this is equivalent to the 25th percentile.
* If "quart" = 2, then this is equivalent to the MEDIAN function.
* If "quart" = 3, then this is equivalent to the 75th percentile.
* If "quart" = 4, then this is equivalent to the MAX function.
* You can use the QUARTILE.EXC function to return the quartile of a data set (exclusive).
* You can use the PERCENTILE.INC function to return the value from a data set that corresponds to a particular percentage (inclusive).
* You can use the PERCENTRANK.INC function to return the rank of a value as a percentage (inclusive).
