What is the lower limit of the modal class of the following frequency distribution?
| Age (in years) | 0 - 10 | 10- 20 | 20 -30 | 30 – 40 | 40 –50 | 50 – 60 |
| Number of patients | 16 | 13 | 6 | 11 | 27 | 18 |
उत्तर
Here the maximum class frequency is 27, and the class corresponding to this frequency is 40-50 So the modal class is 40-50.
Now,
Modal class = 40-50, lower limit (/) of modal class = 40.
Thus, lower limit (/) of modal class is 40
