The following data give the distribution of heights of students :
`{:(underset(("in cm"))"Height",160,150,152,161,156,154,155),(underset("students")"Numbers of ",12,8,4,4,3,3,7):}`
The median of the distribution is

A

154

B

155

C

160

D

161

Text Solution

Verified by Experts

The correct Answer is:
B
Arranging the data in ascending order of magnitude, we obtain

Here, total number of items is `(41+1)/(2)` th=21st item.
From cumulative frequency table, we find that median i.e., 21st item is 155.
