उत्तर
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 stages and along OY, mark number of schools.
Step III: 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 schools.
Step IV: Calculate the height of various bars as follows
| Stage | Height of bars |
| Primary | `80/5` = 16 units |
| Upper Primary | `55/5` = 11 units |
| Secondary | `30/5` = 6 units |
| Higher Secondary | `20/5` = 4 units |
Hence, the required bar graph for the given data is shown below
Scale: 1 unit length = 5 schools
