The term “interquartile range” originates from descriptive statistics and encapsulates the range between the “inter” (or between) “quartiles” (Q1 and Q3) of a dataset. This statistical measure was developed in the 19th century to provide a robust view of the central spread of values in...
In this guide, I will show you how to calculate the interquartile range (IQR) by using Microsoft Excel. I will also show you how to how to calculate the first and third quartiles for a dataset. What is the IQR? The IQR is the difference between the first (25th percentile) and third...

To follow along, download the Excel file:IQR. This dataset is the same as the one I use in the illustration above. This file also includes the interquartile range calculations for finding outliers and the IQR normality test described later in this post. In Excel, you’ll need to use the ...
IQR Calculation using Excel: In Excel, there is no direct way to calculate the Interquartile range. The most common approach is to calculate the third and first quartiles using the quartile function in Excel and then find out the difference (Q3-Q1) between them. ...
Step 4:Now, we calculate the interquartile range (IQR). IQR = Q3-Q1 = 19-8 = 11 Since the IQR is 11, it tells us that the middle 50% of values in the dataset fall within a range of 8 to 19. This means that the values within this range are not very diverse or spread out....

If this formula gives an integer i, take the average of the ith and the next values in the sorted data set. This average is Q3. Finally, the formula for the IQR is Q3 - Q1. How do you find Q1 and Q3 with even numbers? Before we can find the interquartile range, we must find...
Let’s start with the range because it is the most straightforward measure of variability to calculate and the simplest to understand. The range of a dataset is the difference between the largest and smallest values in that dataset. For example, in the two datasets below, dataset 1 has a ra...
The Interquartile Range is defined as the difference between the first quartile (Q1Q_1Q1) and third quartile (Q3Q_3Q3). Mathematically, this is written as: IQR=Q3−Q1IQR = Q_3 - Q_1IQR=Q3−Q1 How to compute the Interquartile in Excel ...
