Find the median for the following frequency distribution:

Text Solution

Verified by Experts

First we will convert the given data in exclusive from :

Here,
N=400
`rArr" " (N)/(2)=(400)/(2)=200`
`rArr` Median class is 165.5-168.5
Now, `l_(1)=165.5l_(2),=168.5,i=168.5-165.5=3,f=136,C=132`
and median `:. M=l_(1)+(((N)/(2)-C))/(f)xxi`
`=165.5+((200-132))/(136)xx3`
`=165.5+(3xx68)/(136)=167`
