Q1 of 55 Page 349

Per day selling prices (in ₹) of Madhu uncle’s shop for the last week were 107, 201, 92, 52, 113, 75, 195; let us find the median of the selling prices.

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,


52, 75, 92, 107, 113, 195, 201


Note that, total number of data, n = 7


Here, n is odd.


When n is odd, median is found out as



Putting n = 7, we get




Median = 4th term


Note in the ascended order list, 4th term is 107.


1st term = 52,


2nd term = 75,


3rd term = 92,


4th term = 107 ß


Thus, median is 107.
