MCQ
The median class for the following data is
| Class interval | 20-40 | 40-60 | 60-80 | 80-100 |
| Frequency | 10 | 12 | 20 | 22 |
- A$20-40$
- B$40-60$
- ✓$60-80$
- D$80-100$
✓
Answer
Correct option: C.
$60-80$
(c) : The cumulative frequency distribution table from the given data can be drawn as :
Here, $n=64 \Rightarrow \frac{n}{2}=32$
So, the median class is $60-80$.
| Class interval | Frequency | Cumulative frequancy |
| 20-40 | 10 | 10 |
| 40-60 | 12 | 22 |
| 60-80 | 20 | 42 |
| 80-100 | 22 | 64 |
Here, $n=64 \Rightarrow \frac{n}{2}=32$
So, the median class is $60-80$.
