In Fig. 14.2, there is a histogram depicting daily wages of workers in a factory. Construct the frequency distribution table.
Solution:
Given, the histogram represents the daily wages of workers in a factory.
We have to construct a frequency distribution table
From the histogram,
We observe that the class interval is 150 - 200, 200 - 250,.. with a width as 50.
The frequency distribution table is given below,
| Wages (in Rupees) | Number of Workers |
| 150 - 200 | 50 |
| 200 - 250 | 35 |
| 250 - 300 | 40 |
| 300 - 350 | 20 |
| 350 - 400 | 10 |
Total number of workers = 50 + 35 + 40 + 20 + 10 = 145
