In this article, we will learn How to use the QUARTILE function in Excel.
Quartile of a number
The group of quarters which is 1/4th of the total. For example, consider 200 total marks. First quartile is between 0 and 50 (25% of the 200). Second quartile is between 51 and 100. Third percentile is between 101 and 150 and the last fourth quartile is between 151 and 200. Students scoring in these ranges will be grouped under that quartile.
You can extract the exact percentile borders and apply required steps. Let's learn the QUARTILE function and illustrate the function using an example
QUARTILE Function in Excel
Quartile function returns the nth percentile of the range of values.
It returns minimum value, 1/4th quartile value, 1/2th quartile value, 3/4th value & maximum value using the quart argument.
QUARTILE Function Syntax:
array : list of scores given as array reference. Like C2:C18
quart : a number showing the percentile value
|Quart value||Nth percentile|
|0||0th percentile or Min Value|
|4||100th percentile or Max Value|
All of these might be confusing to understand. Let's understand how to use the function using an example. Here
The nth percentile value for the range of values : 0,1,2,3,4
Use the formula:
The red cells are the negative numbers provided in different formatting styles.
Now we wish to find the quartile of the data set
Use the formula
As you can see the quartile of the range using the Excel Quartile function.
Difference with the percentile function
PERCENTILE function calculates the exact percentile depending upon the percentile value.
Here we have a set of values as data ( A1 : A23 ) and we need to find some percentile values from the array.
Use the formula:
|= PERCENTILE ( data , D3)|
data - array given using named range.
D3 - value of k given as cell reference.
The function returns the 0th percentile value or minimum value which is 28 .
Now copy the formula to get different percentile values of the range to the remaining cells and formula as shown in the snapshot below.
As you can see the results in the snapshot above.
