To find median, Assume

Σfi = N = Sum of frequencies,

h = length of median class,

l = lower boundary of the median class,

f = frequency of median class

and Cf = cumulative frequency

Lets form a table.

So, N = 67

N/2 = 67/2 = 33.5

The cumulative frequency just greater than (N/2 = ) 33.5 is 42, so the corresponding median class is 125 - 145 and accordingly we get Cf = 22(cumulative frequency before the median class).

Now, since median class is 125 - 145.

l = 125, h = 20, f = 20, N/2 = 33.5 and Cf = 22

Median is given by,

= 125 + 11.5

= 136.5

Thus, median is 136.5.
