Draw a bar graph from the above information.
ANSWER:
We can draw the bar graph by following the given steps:
Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.
Step 2.- Along OX, write the names of the subjects at the points that are taken at a uniform gap.
Step 3.- Choose the scale:
1 big division = 10 marks
1 small division = 1 mark
Step 4.- Heights of the various bars are:
Hindi = 43 small divisions = 4 big divisions and 3 small divisions
English = 56 small divisions = 5 big divisions and 6 small divisions
Maths = 80 small divisions = 8 big divisions
Science = 65 small divisions = 6 big divisions and 5 small divisions
Social Science = 50 small divisions = 5 big divisions
Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.
