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 $25^{th}$ percentileA percentile is a number that compares one score to the scores of the rest of the group. It displays the percentage by which a given score exceeds the other scores. For example, if a user’s score is in the 90th percentile for a test, it means that the user scored better than 90% of people who took the test. of the data. The upper end of the box represents the third quartile (or Q3), i.e., the $75^{th}$
