Question

4) Find the mean and median of 5, 3, 12, 0, 7, 11, 4, 3, 9.​

Answer 1

0,3,3,4,5,7,9,11,12

mean=(0+3+3+4+5+7+9+11+12)/9

54/9

mean=6

median=(n+1/2)th term

{(9+1)/2}th term

(10/2) th term

5th term

median =5

mean=6

median=5

Answer 2

Step-by-step explanation:

Mean =        Sum of Numbers

            ------------------------------------------

                   Quantity of Numbers

       =       5 + 3 + 12 + 0 + 7 +  11 + 4 +  3 + 9 / 9

       =       54 / 9

       =        6

Therefore, mean of this data is 6.

Median = 12, 11, 9, 5, 4, 3, 3, 0

            = 5

Therefore, number in the middle (median) is 5
