Answer: 5
Put the numbers in order
Before: 5, 2, 9, 7, 4
After: 2, 4, 5, 7, 9
Use your left and right pointer finger. Put your left finger on 2 and your right finger on 9.
Your left pointer moves to the right on 4. Your right pointer moves to the left on 7.
The middle number is 5 so 5 is the median.
