Answer:
The median is the middle number; found by ordering all data points and picking out the one in the middle.
You want to put the numbers in order:
47, 49, 49, 50, 52, 57, 57, 57, 61
Then you go one number at a time from both ends until you get into the middle:
47, 49, 49, 50, 52, 57, 57, 57, 61
47, 49, 49, 50, 52, 57, 57, 57, 61
47, 49, 49, 50, 52, 57, 57, 57, 61
47, 49, 49, 50, 52, 57, 57, 57, 61
47, 49, 49, 50, 52, 57, 57, 57, 61
So the answer is 52.
Tip: when you do this and you are left with two numbers that are in the middle, add them and divide them by 2.
