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 |
60 Number of patients | 16 | 13 | 6 | 11 | 27 | 18 |
Here, the maximum class frequency is 27.
The class corresponding to this frequency is the modal class. ⇒ modal class = 40 - 50
∴ lower limit of the modal class (l) = 40
