Given that
Variates = 5, 7, 8, 11, 13, 17
Frequency = 3, 7, 7, 12, 13, 10
Thus
as we know
Total Number of variates = 6
Thus Center two variates are 8 and 11
And Frequencies are 7 and 12
So Median = 7+12/ 2
= 19/2 = 95.5
Variates = 5, 7, 8, 11, 13, 17
Frequency = 3, 7, 7, 12, 13, 10
Thus
as we know
Total Number of variates = 6
Thus Center two variates are 8 and 11
And Frequencies are 7 and 12
So Median = 7+12/ 2
= 19/2 = 95.5

This is not the correct way to compute median in a discrete series.

Solution :-
Median -
_____________________________________________________________
x Frequency Cumulative Frequency
_____________________________________________________________
5 3 3
7 7 10
8 7 17
11 12 29
13 13 42
17 10 52
___________________________________________________________
N = 52
___________________________________________________________
Median = Size of (N + 1)/2th item
⇒ (52+1)/2th item
⇒ 53/2th item
⇒ size of 26.5th item = 11
So, Median is 11
