What is the median of 7, 3, 4, 7, 5, 6, 5, 6, 5, 4?
How to calculate median:
Arrange mumbers in numerical order
Count how many numbers there are
If the total is odd, divide by 2 and round up to get the position of the median number
If the total is even, divide by 2. Go to the number and average it with the number in the next higher positon to get the median
So in this case:
3,4,4,5,5,5,6,6,7,7
There are 10 numbers
10/2=5. Average out with the next higher number ((5+5)/2=5)← (mean average)
So this leaves us with the answer of median=5.
