Q3 of 55 Page 349

The marks obtained by 14 students are 42, 51, 56, 45, 62, 59, 50, 52, 55, 64, 45, 54, 58, 60; let us find the median of the obtaining marks.

To find median, it is necessary to arrange the data in either ascending or descending order.

So, let’s arrange the data into ascending order. It is,


42, 45, 45, 50, 51, 52, 54, 55, 56, 58, 59, 60, 62, 64


Note that, total number of data, n = 14


Here, n is even.


When n is even, median is found out as



Putting n = 14, we get



⇒


⇒


⇒


⇒ Median = 54.5


Thus, median is 54.5.
