26
27
Frequency

Here, the maximum frequency is 6 and it is of observation 22. So, the mode, i.e., modal marks, is 22.
| Observation | 14 | 15 | 16 | 17 | 19 | 20 | 22 | 24 | 26 | 27 |
| Frequency | 1 | 3 | 2 | 2 | 1 | 1 | 6 | 1 | 1 | 2 |
Here, the maximum frequency is 6 and it is of observation 22. So, the mode, i.e., modal marks, is 22.
