Step 1

Box and whisker plot:

A type of graph used to display patterns of quantitative data is called a boxplot. Sometimes it is also called box and whisker plot. A boxplot splits the data into quartiles. The body of the boxplot consists of a box, which goes from the first quartile (Q1) to the third quartile(Q3). The vertical line in the boxplot is drawn at Q2, the median of the data set.
