|---|---|
| 150 - 200 | 10 |
| 200 - 250 | 5 |
| 250 - 300 | 7 |
| 300 - 350 | 4 |
| 350 - 400 | 3 |
Answer
Steps of construction of histogram:
Since, the scale on x-axis starts at 150, a break (kink) is shown near the origin on x-axis to indicate that the graph is drawn to scale beginning at 150.
Take 2 cm along x-axis = 50 units.
Take 1 cm along y-axis = 2 units.
Construct rectangles corresponding to the above continuous frequency distribution table.
The required histogram is shown in the below figure :
