Question
The following frequency distribution table shows the cost of living in a city in a period of 2years. Draw histogram for this frequency distribution:
| Cost of living | 2000 - 2500 | 2500 - 3000 | 3000 - 3500 | 3500 - 4000 | 4000 - 4500 | 4500 - 5000 | 5000 - 5500 | 5500 - 6000 |
| No. of months | 3 | 4 | 2 | 5 | 3 | 2 | 4 | 1 |
Solution
We represent the class limits on the x-axis on a suitable scale and the frequencies on the y-axis on a suitable scale. Taking class intervals as bases and the corresponding frequencies as heights, we construct rectangles to obtain a histogram of the given frequency distribution.
Here as the class limits do not start from 0, we put a kink between 0 and the lower boundary of the first class.
