- None of these
Explanation
Median is the middle value after sorting numbers from smallest to biggest.
Given numbers: 1, 2, 3, 4, 5, 6, 2, 1, 7
Step 1: Arrange in order: 1, 1, 2, 2, 3, 4, 5, 6, 7
Step 2: Count total numbers = 9, which is odd
Step 3: Middle position = (9 + 1) ÷ 2 = 5th position
Step 4: 5th number in ordered list = 3
So median = 3
