Question

Find the median of 21,3,5,16,17,9,18,12,2,19,12,25,15
​

Answer 1

Answer:

Median = 12

Step-by-step explanation:

Arrange given numbers in ascending order

2 3 5 9 12 12 15 16 17 18 19 21 25

Then find the middle value of the arranged order

12

Answer 2

• We have to evaluate the above expression by using the given data.

              Given data:- $21,3,5,16,17,9,18,12,2,19,12,25,15.$

              To find:- Median of given data.

              Solution:-

•  To find the median first we have to arrange the given term in ascending order.

         $=>2,3,5,9,12,12,15,16,17,18,19,21,25.$

            Here a number of observations are n=13.

            since n is odd

            The formula of Median is,

              $\text { median }=\left(\frac{n+1}{2}\right)$

            Therefore,

            $\text { median }=\left(\frac{13+1}{2}\right)\\\text { median }=\left(\frac{14}{2}\right)\\\text { median }=\left7\right$

          Hence we will get in seventh position median is $15.$
