Question
The following table gives production yield in kg per hectare of wheat of 100 farms of a village :
| Production yield (kg/hectare) : |
40−45 | 45−50 | 50−55 | 55−60 | 60−65 | 65−70 |
| Number of farms | 4 | 6 | 16 | 20 | 30 | 24 |
Change the distribution to a 'more than type' distribution, and draw its ogive.
Solution
| Production yield | Cumulative frequency |
| more than 40 | 100 |
| more than 45 | 96 |
| more than 50 | 90 |
| more than 55 | 74 |
| more than 60 | 54 |
