Get Tukey Five-Number Summaries in R (Example) | fivenum() Function


In this tutorial, I’ll illustrate how to calculate Tukey five-number summaries using the fivenum function in the R programming language.

The article consists of one example for the application of the fivenum function. To be more specific, the article will contain these topics:

So now the part you have been waiting for – the example.


Example Data

At first, I need to create some data that we can use in the examples below:

vec <- rnorm(100)
# [1] -1.83448649  0.28559301 -0.54080526 -0.39577168  0.05639552 -0.09803291

Have a look at the previous output of the RStudio console. It shows that the example data is a numeric vector containing randomly distributed values.


Example: Get Tukey Five-Number Summaries Using fivenum() Function

In this example, I’ll explain how to return the Tukey five-number summaries in R, i.e. the minimum, lower-hinge, median, upper-hinge, and maximum of a data object.

For this task, we can apply the fivenum function as shown below:

fivenum(vec)                     # Apply fivenum function
# [1] -2.6421637 -0.7640363 -0.1211748  0.3963059  2.3108042

The previous output shows the Tukey five-number summaries of our input vector.
