What is Box and Whisker Plot?

Box and Whisker Plot is defined as a visual representation of the five-point summary. The Box and Whisker Plot is also called as Box Plot. It consists of a rectangular “box” and two “whiskers.” Box and Whisker Plot contains the following parts:

• Box: The box in the plot spans from the first quartile (Q₁) to the third quartile (Q₃). This box contains the middle 50% of the data and represents the interquartile range (IQR). The width of the box provides insights into the data’s spread.
• Whiskers: The whiskers extend from the minimum value to Q₁ and from Q₃ to the maximum value. They signify the range of the data, excluding potential outliers. The whiskers can vary in length, indicating the data’s skewness or symmetry.
• Median Line: A line within the box represents the median (Q₂). It divides the data into two halves, revealing the central tendency.
• Outliers: Individual data points lying beyond the whiskers are considered outliers and are often plotted as individual points.

What is a Five-Point Summary?

The five-point summary rundown comprises five key measurements: the base worth, the principal quartile (Q₁), the middle (Q₂), the third quartile (Q₃), and the greatest worth. These measurements partition a dataset into four similarly estimated parts, uncovering important data about the dataset’s focal inclination, spread, and skewness.
