The following table gives production yield per hectare of wheat of 100 farms of a village
Production yield (in kh/ha) | 50 – 55 | 55 - 60 | 60 - 65 | 65 - 70 | 70 - 75 | 75 - 80 |
Number of farms | 2 | 8 | 12 | 24 | 38 | 16 |
Change the distribution to a more than type distribution, and draw its ogive
The frequency distribution table of more than type graph is as follows:
Production yield (lower class limits) | Cumulative frequency |
More than or equal to 50 | 100 |
More than or equal to 55 | 98 |
More than or equal to 60 | 90 |
More than or equal to 65 | 78 |
More than or equal to 70 | 54 |
More than or equal to 75 | 16 |
Now,
Taking lower limit on x-axis,
Cumulative Frequencies on y- axis,
Its ogice can be drawn as:
