Q. 84.7( 3 Votes )
Following is the distribution of I.Q of 100 students. Find the median I.Q.
Answer :
To find: The median I.Q.
Formula Used:
Median = l + 
× h
l = lower limit of median class
f = frequency of median class
h = size of the median class
F = cumulative frequency preceding the median class.
Explanation:
We have, N = 100
= 50
The cumulative frequency just greater than 
is 67 then the median class 94.5-104.5 such that,
l = 94.5, f = 33, F = 34, h = 104.5 – 94.5 = 10
= 94.5 + 4.85
= 99.35
