Q5 of 71 Page 206

Find the median of the following frequency distribution.

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


Now, the sum of all frequencies = 160


And,




⇒ m = 80


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


Which is 105 and then we’ll see the corresponding marks obtained and that will be the median.


⇒ Median = 35
