Question

# The following data gives the distribution of height of students

The median of the distribution is[AMU 1994]</span

- 154
- 155
- 160
- 161

## The correct answer is: 155

### Arranging the data in ascending order of magnitude, we obtain

Here, total number of items is 41 i.e., an odd number.

Hence, the median is th i.e., 21^{st} item.

From cumulative frequency table, we find that median

i.e., 21^{st} item is 155,

(All items from 16 to 22^{nd} are equal, each 155).
