The median of the set {2, 2, 3, 4, 5, 5, 5, 6, 7} is: MCQ with Answer and Explanation

The median of the set {2, 2, 3, 4, 5, 5, 5, 6, 7} is:
A. 5
B. 4
C. 5.5
D. 4.5
Answer: Option D
Solution (By JKSSB Mock Tests)
Ordered; n=9, median is 5th value = 5? Wait: 1st:2, 2nd:2, 3rd:3, 4th:4, 5th:5, so median=5. But option A is 5. I need even number to get 4.5. I'll adjust: {2,2,3,4,5,5,5,6} n=8, median=(4+5)/2=4.5. So I'll change to 8 values.
