Question

Find the median of the following data
2,10,9,9,5,2,3,7,11

Answer 1

First we arrange it in ascending order
2, 2, 3, 5, 7, 9, 9, 10, 11
So, we have nine observations.
And the number which lies in middle is 7.
So,mediam is 7.
Hope it helps...!!!

Answer 2

median = 7 +7 /2
= 14 /2
= 7 is the correct answer
