Let us find the median.

To find out median, we need to calculate cumulative frequency for the given data.

Let us make a table for that.



Here, n = 116, that is, n = even.


Since, n is even, median can be found out as:



⇒


⇒ Median = The mean of 58th and 59th observations


And we know that, 58th observation = 2 [∵ 58 comes between 51 and 86]


And 59th observation = 2 [∵ 41 comes between 51 and 86]


Median = Mean of 2 and 2


⇒


⇒


⇒ Median = 2


Thus, median = 2.
