# 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 = 70, that is, n = even.

Since, n is even, median can be found out as:  Median = The mean of 35th and 36th observations

And we know that, 35th observation = 47 [ 35 comes between 32 and 44]

And 36th observation = 47 [ 36 comes between 32 and 44]

Median = Mean of 47 and 47  Median = 47

Thus, median = 47.
