Class Frequency c.f
0 - 10 4 4
10 - 20 4 8
20 - 30 8 16
30 - 40 10 26
40 - 50 12 38
50 - 60 8 46
60 - 70 4 50.
Now,
N = 50, N/2 = 25.
Now we should find a value whose cf should be greater than N/2 = 25.In the above cf 26 > N/2 = 25
Therefore Median class = 30 - 40.
Hope this helps!

Hey there!
The median of the given data is the Class containing the middle frequency .
Sum of frequencies = = 4 + 4 + 8 + 10 + 12 + 8 + 4 = 50 .
Now , The median = 25th frequency .
25th frequency lies in 4th class [ 30-40 ]
Therefore, Median class = 30 - 40 .
Note : You can do this by finding Cumulative Frequency as well
