What is the definition of box-and-whisker plot?

A box-and-whisker plot, also known as a box plot, is a graphical representation of a dataset that summarizes its distribution through five key statistics: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. The "box" displays the interquartile range (IQR), which contains the middle 50% of the data, while the "whiskers" extend to the minimum and maximum values, excluding outliers. This plot is useful for visualizing the spread and skewness of the data and for identifying potential outliers.
