Violin Plot

Getting started with violin plots

A violin plot is a combination of a boxplot and a density plot, and it shows the distribution of numerical data. Unlike boxplots, which display only summary statistics, violin plots provide summary statistics and the density of each variable.

Let’s study the structure of the violin plot:

• The white circle in the center of the violin plot represents the median.
• The length of the box, i.e., the dark green bar, shows the Interquartile range (IQR).
• The area surrounding the boxplot displays the estimated kernel densityKernel density estimation (KDE) is a mathematical technique for estimating the probability density function of a given random variable. It is a method for creating a smooth curve for the given dataset. to display the data distribution.

In violin plots, the broader areas indicate a higher probability, while the skinnier sections indicate a lower probability. It also summarizes the data using five summary values:

• The minimum
• The maximum
• The median
• The first and third quartiles

We will use the warpbreaks dataset, which comprises of $54$ observations on the ...
