Question

Given below is a table which shows the year wise strength of a school. Represent this data by a bar graph.

Year	2011-12	2012-13	2013-14	2014-15	2015-16
No. of students	800	975	1100	1400	1625

Answer 1

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 years at the points that are taken at a uniform gap.

Step 3.- Choose the scale:
1 big division = 100 students
1 small division = 10 student

Step 4.- Heights of the various bars:
2011-2012 = 80 small divisions = 8 big divisions
2012-2013 = 97.5 small divisions = 9 big divisions and 7.5 small divisions
2013-2014 = 110 small divisions = 11 big divisions
2014-2015 = 140 small divisions = 14 big divisions
2015-2016 = 162.5 small divisions = 16 big divisions and 2.5 small divisions

Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.

We get the following bar graph:
