Answer 1

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum.

In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.

Therefore,

The point A represents the first quartile, Q₁.

The point B represents the median, Q₂

The point C represents the third quartile, Q₃.
