Boxplot

Overview of the boxplot

A box and whisker plot (commonly known as a boxplot) is used to visualize multiple distributions using summary statistics. A boxplot provides information on the five summary statistics of the given dataset variable, which include:

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

In short, a boxplot is popularly used to display data distribution. It helps detect outliers and compare distributions of the data.

Let’s study the structure of the boxplot:

• The box, as seen from the figure, is the core of the boxplot.
• The lower side of the box represents the first quartile (or Q1), i.e., the $25^{th}$
