Solution

We choose 1 small division to represent 1 child in the graph.

Mark the horizontal axis OX as “Subject” and the vertical axis OY as “Marks”.

Along the horizontal axis OX, choose bars of uniform (equal) width, with a uniform gap between them.

Choose a suitable scale to determine the heights of the bars,according to the space available for the graph. Here, we choose 1 big division to represent 10 marks.

Answers :-

(i) In Maths, the students showed their greatest improvement.
