Question 89(i)
The table below compares the population (in Hundreds) of 4 towns over two years:
Study the table and answer the following question:
Draw a double bar graph using appropriate scale to depict the above information.
Steps to construct the bar graph are as follows:
Step I We draw two lines perpendicular to each other on a graph paper and call them horizontal and vertical axes.
Step II Along the horizontal axis OX mark the town and along the vertical axis, OY mark the population.
Step III We choose a suitable scale to determine the heights of bars. Here, we choose the scale as 1 small division to represent 500.
Step IV First, we draw the bars for the year 2007 and the bars for years 2009 for different towns.
Bars for the year 2007 and 2009 are shaded separately and the shading is shown in the top right corner of the graph paper.
