1. The value of the middle-most observation is called the median of the data.
First arrange the given numbers in ascending order,
2,2,3,5,7,9,9,10,11
Here n=9, which is odd.
Where, n is the number of the given number.
∴ median = value of
1/2 (n+1) th observation.
= 1/2(9+1)
= 1/2(10)
=10/2
=5
Then, value of 5 thterm =7
Hence, the median is 7.
