Where

c f =

cumulative frequency
Median

= L + ⎩ ⎨ ⎧ h \times \frac{( \frac{N}{2} - c f )}{f} ⎭ ⎬ ⎫

Here

N = 49

N /2 = 24.5

c f

just greater than

24.5

26

Median class

= 15 - 20

So,

L = 15, h = 5, f = 15

and

c f = c f

of preceding class i.e

11

Substitute all the value in the above formula, we get
Median

= 15 + {5 \times (24.5 - 11) /15}

15 + 4.5

= 19.5

Thus, median of frequency distribution is

19.5
