Let us take an example which gives us the marks scored by 50 students of a class, in an exam out of 100.

The following table gives us the information about the data.

Here the first class interval is 0 - 10. So the class preceeding it would lie on the negative X axis. The midpoint of the first class interval i.e. B is joined to this point with 0 frequency on the negative axis.
