# QUARTILE.INC Function

Returns the quartile of a given data set based on percentile values from 0.1 inclusive

## What is the QUARTILE.INC Function?

The QUARTILE.INC Function is categorized under Statistical functions. It will return the quartile of a given data set based on percentile values from 0.1 inclusive. The function bases its calculation on a percentile range of 0 to 1 inclusive.

As a financial analyst, QUARTILE.INC can be used to find out the minimum and maximum revenue for a quarter for a given population. The function can also be used in revenue analysis.

### Formula

=QUARTILE.INC(array,quart)

The QUARTILE.INC function uses the following arguments:

1. Array (required argument) – It is the array or cell range of data values for which we want the quartile value.
2. Quart (required argument) – It indicates which value shall be return. It is an integer between 0 and 4, representing the required quartile.

QUARTILE.INC is closely related to the PERCENTILE.INC function. It accepts five values for the quart argument, as shown in the table below:

QuartReturn value
0Min value
1First quartile – 25th percentile
2Median value – 50th percentile
3Third quartile – 75th percentile
4Max value

### How to use the QUARTILE.INC Function in Excel?

To understand the uses of the QUARTILE.INC function, let’s consider an example:

#### Example 1

Suppose we are given the following revenue figures:

QUARTILE.INC can return the minimum value, first quartile, second quartile, third quartile, and max value. The function accepts five values for the quart argument, as shown below:

The formula used was:

Similarly, we used 1 for the 25th percentile, 2 for the 50th percentile, 3 for the 75th percentile and 4 for the Max value.

### Few notes about the QUARTILE.INC Function

1. #NUM! error – Occurs if either:
• The given value of quart is < 0 or > 4; or
• The given array is empty.
2. #VALUE! error – Occurs if the given value of quart is non-numeric.
3. From Excel 2010, the QUARTILE.EXC and QUARTILE.INC functions would replace the QUARTILE function, which is now classified as a compatibility function.
4. The QUARTILE.INC and QUARTILE.EXC functions both find a requested quartile of a supplied data set. The difference between these two functions is that QUARTILE.INC bases its calculation on a percentile range of 0 to 1 inclusive, whereas QUARTILE.EXC bases its calculation on a percentile range of 0 to 1 exclusive.
5. If the requested quartile falls between two of the values in the supplied array, MS Excel interpolates between these values to calculate the quartile value.
