Find the median of the following:

Firstly, we’ll find the cumulative frequencies (c.f) –


Now, the sum of all frequencies = 245


And,




⇒ m = 123


Now we’ll see to the c.f just greater than this m


Which is 150 and then we’ll see the corresponding marks obtained and that will be the median.


⇒ Median = 0.4
