MCQ
The median class for the data given below is:
| Class | 20- 40 | 40 - 60 | 60 - 80 | 80 - 100 | 100 - 120 |
| Frequency | 10 | 12 | 14 | 13 | 17 |
- A80 - 100
- ✓60 - 80
- C
- D40 - 60
✓
Answer
Correct option: B.
60 - 80
(B) 60 - 80
Explanation: Total frequencies (N) = 10 + 12 + 14 + 13 + 17= 66
So, $\frac{N}{2}=\frac{66}{2}=33$
c.f. Just greater than 33 is 36 and the corresponding class is 60 - 80
hence, median class = 60 - 80
