While dealing with any statistical data analysis project, there are many handy tools you can apply. The basic idea is to identify the question and use the necessary function to answer that question. For example, if the data distribution needs to be seen, the ideal answer is to plot a data distribution function.

If it is necessary to see the values and compare them with the other columns’ value, the best way is to plot a bar plot or histogram. But what if a statistical query needs to be satisfied? The trend can be observed in a distribution function, but there is no easy way out if we need to check a specific percentile of data.

Boxplot comes as a solution to the above problem. Boxplots are used to describe the attribute’s percentile values, as per the column it is plotted against. Boxplot can be quite insightful in rule-based model engineering as well as exploratory data analysis in general.

Boxplot deals with quartiles.

Let us first plot a pandas boxplot and then understand the parts of it.
