Answer : The correct option is, (C) 19

Step-by-step explanation :

Median : It is the middle term that is sorted by the list of numbers. It is determine by placing the numbers in increasing order.

For odd observations the formula will be:
(n+1)/(2)

For even observations the formula will be:
(n)/(2)+1^(th)\text{ term}

As we are given that the set of data:

13, 15, 25, 17, 19, 20, 33

First we have to placing the numbers in increasing order.

13, 15, 17, 19, 20, 25, 33

Now we have to determine the median.

For odd data:


(n+1)/(2)

n = 7


\Rightarrow (7+1)/(2)=(8)/(2)=4


4^(th)\text{ term}

The number at 4th position is, 19

Thus, the median of the given set of data of values is, 19
