First arrange in it ascending order= 2,2,3,5,7,9,9,10,11.
No of observations = 9(odd)
Therefore median = (n+1/2)th term.
= 9+1/2
=10/2
=5th term
=7 is the answer.
hope it will help u :)

Hi there!
_______________________
Median of ungrouped data :
After arranging the given data in an ascending or descending order of magnitude the value of the middle most observation, is called the median of data.
Solution :
3, 11, 7, 2, 5, 9, 9, 2, 10.
Arranging the data in ascending order, we have :
2, 2, 3, 5, 7, 9, 9, 10, 11.
Here, n = 9, which is odd.
∴ Median = Value of
term.
⇒
term.
⇒
term.
⇒ value of 5th term.
Hence, the median of the data is 7.
