Question

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

Year	2005-2006	2006-07	2007-08	2008-09	2009-10
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:
2005−2006 = 80 small divisions = 8 big divisions
2006−2007 = 97.5 small divisions = 9 big divisions and 7.5 small divisions
2007−2008 = 110 small divisions = 11 big divisions
2008−2009 = 140 small divisions = 14 big divisions
2009−2010 = 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:
