Find the median for the given data set

4,8,9, 12. 31. 4, 16, 17, 11

31

Step-by-step explanation:

Median - The "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. Put them in order: {10, 11, 13, 15, 16, 23, 26} The middle number is 15, so the median is 15.

11

Step-by-step explanation:

Arranging in order. 4,4,8,9,11,12,16,17,31

Number (N) = 9

Using formula,

(N+1) / 2

(9+1) / 2

10/2

5

Now 5th number is 11 in the arranged data so answer is 11
