Someone explain how to figure out mean and median ?

How to figure out Mean:

Add all numbers together then divide by how many numbers there are.

EXAMPLE:

2+4+6+8= 20

4 / 20 = 5

Mean = 5

How to figure out the Median:

The median is the middle number for example:

2, 3, 7, 5, 1, 9, 0

Now place them in order:

0, 1, 2, 3, 5, 7, 9

eliminate one from each side till you got just one number

0 and 9

1 and 7

2 and 5

3 is left so median is 3
