Let's try using this knowledge to find the interquartile range for a data set in the following two examples. The first example will show how to find the IQR with an odd number of values in a data set, while the second example will show how to find the IQR with an even number of...
In this guide, I will show you how to find the interquartile range (IQR) in SPSS. I will also show you how to find the first (Q1) and third (Q3) quartiles.

Variability helps us understand how far apart each data point is from the other and its distance from the center of a distribution. It is also referred to as spread, scatter, or dispersion. It is most commonly measured with variance, standard deviation, range, and interquartile range. Variance...
This article explains how to compute an Interquartile Range (IQR) in the R programming language.The tutorial is mainly based on the IQR() R function. So let’s have a look at the basic R syntax and the definition of IQR() first:...
Step 5:Find the Interquartile Range IQR value. To find the Deduct Q1 value from Q3. IQR = Q3-Q1 Step 6:Find the Inner Extreme value. An end that falls outside the lower side which can also be called as a minor outlier. Multiply the IQR value by 1.5 and deduct this value from Q1...
Find Q1 (the median of the set of numbers below the median): 3, 5, 7, 8, 9. Find Q3 (the median of the set of numbers above the median): 11, 15, 16, 20, 21. Subtract Q1 from Q3 : 16 – 7 = 9. Solution: The IQR is 9. Back to Top Find an interquartile range for ...
