Solution:
To make a line plot, we consider a set of data.
Suppose marks of 25 students in class in General knowledge test,out of 20 is as follows:
11, 12, 12, 9, 8, 16, 18, 17, 20, 20, 13, 13, 8,9,10, 10, 14, 14, 15, 15, 19, 19, 17, 18,20.
To draw the line plot, we make an interval or sub interval, and represent these points through certain notation.
8 9 10 11 12 13 14 15 16 17 18 19 20

The line plot is used for Quantitative data.
