# Let us find the m

Answer :

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.
