Draw a histogram to represent the following frequency distribution of monthly wages of 255 workers of a factory.
Monthly wages (in rupees) | No. of workers |
---|---|
850 - 950 | 35 |
950 - 1050 | 45 |
1050 - 1150 | 75 |
1150 - 1250 | 60 |
1250 - 1350 | 40 |
Answer
Steps of construction of histogram :
Since the scale on x-axis starts at 850, a kink is shown near the origin on x-axis to indicate that the graph is drawn to scale beginning at 850.
Take 2 cm along x-axis = 100 rupees.
Take 1 cm along y-axis = 10 workers.
Construct rectangles corresponding to the above continuous frequency distribution table.
The required histogram is shown in the adjoining figure.
