Question

Find median 17 32 35 33 15 12 21 38 40 24 37 30

Answer 1

therefore 30 and 32 are the median.

Answer 2

Answer:

31

Step-by-step explanation:

We will start by arranging the observations in ascending order of magnitude i.e. 12 15 17 21 24 30 32 33 35 37 38 40

Let the no. of observations be n.

Then, n = 12

When the no. of observations is even, the median is calculated by taking the average of (n/2) and (n/2 + 1).

Thus, n/2 = 12/2 = 6

n/2 + 1 = 12/2 + 1 =7

Now we take the average of the 6th and 7th observation i.e. 30 and 32

Average = Sum of observations / Total no. of observations

               =30 + 32/ 2   = 62/2    =31

Ans.31
