What is the mean ? i don’t need work but it could help

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.

529 and 531
