Solution
In order to construct a bar graph representing the above data, we follow the following steps:
Step I: Take a graph paper and draw two mutually perpendicular lines OX and OY. Let OX as the horizontal axis and OY as the vertical axis.
Step II: Along OX, mark bank names and along OY, mark number of ATMs.
Step III: Along OX, choose the uniform (equal) width of the bars and the uniform gap between them, according to the space available for the graph.
Step IV: Choose a suitable scale to determine the heights of the bars, according to the availability of space. Here, we choose 1 unit length represents 5 ATMs.
Step V: Calculate the height of various bars as follows:
| Bank | Height of bars |
| Syndicate Bank | `5/5` = 1 unit |
| Dena Bank | `15/5` = 3 units |
| Indian Bank | `20/5` = 4 units |
| State Bank of India | `25/5` = 5 units |
| Vijaya Bank | `10/2` = 2 units |
Hence, the required bar graph of given data is shown below
Scale: 1 unit length = 5 ATMs
