Question
Refer to question $23.$ Prepare a bar graph of the data.
✓
Answer
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 number of two wheelers and along $OY,$ mark number of families.
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: Calculate the height of various bars as follows:
Hence, the required bar graph for the given data is shown below:
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 number of two wheelers and along $OY,$ mark number of families.
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: Calculate the height of various bars as follows:
| Number of two wheelers | Height of bars |
| $0$ | $\frac{3}{1}=1.5\text{ units}$ |
| $1$ | $\frac{28}{2}=14\text{ units}$ |
| $2$ | $\frac{14}{2}=7\text{ units}$ |
| $3$ | $\frac{4}{2}=2\text{ units}$ |
| $4$ | $\frac{1}{2}=0.5\text{ units}$ |
