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.
In descriptive statistics, the interquartile range tells you the spread of the middle half of your distribution.Quartiles segment any distribution that’s ordered from low to high into four equal parts. The interquartile range (IQR) contains the second and third quartiles, or the middle half ...
Finding the interquartile range in R is a simple matter of applying the IQR function to the data set, you are using. It has the format of IQR(data set) and returns the interquartile range for that data set. Its companionsummary functionhas the format of summary(data set) and returns th...
Thisinterquartile rangecalculator finds the IQR for you, along with the 25th percentile, the 50th percentile (the median) and the 75th percentile. The calculator then subtracts the 75th percentile from the 25th percentile to find the interquartile range using the formula Q3– Q1= IQR. Just typ...
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...
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:...
2. Next, we need to calculate Q3. To calculate Q3 in Excel, simply find an empty cell and enter the formula ‘=QUARTILE(array, 3)‘. Again, replacing the ‘array‘ part with the cells that contain the data of interest. 3. Finally, to calculate the IQR, simply subtract the Q1 value...
