QUARTILE.INC function

Returns the quartile of a data set, based on percentile values from 0 to 1, inclusive. Quartiles often are used in sales and survey data to divide populations into groups. For example, you can use QUARTILE.INC to find the top 25 percent of incomes in a population.

Syntax

QUARTILE.INC(array,quart)

Argument	Description	Remarks
array	The array or cell range of numeric values for which you want the quartile value.	If array is empty, QUARTILE.INC returns the #NUM! error value.
quart	Indicates which value to return.	If quart equals 0, QUARTILE.INC returns the minimum value. If quart equals 1, QUARTILE.INC returns the first quartile (25th percentile). If quart equals 2, QUARTILE.INC returns the median value (50th percentile). If quart equals 3, QUARTILE.INC returns the third quartile (75th percentile). If quart equals 4, QUARTILE.INC returns the maximum value. If quart < 0 or if quart > 4, QUARTILE.INC returns the #NUM! error value. If this argument contains a decimal value, this function ignores the numbers to the right side of the decimal point.

General remarks

MIN, MEDIAN, and MAX return the same value as QUARTILE.INC when quart is equal to 0 (zero), 2, and 4, respectively.
