Mu is μ.

To find μ there many ways, but here I will show you the basic.

Let us say we have this set of numbers.

1,2,3,4,5,5,6,6,7,7,8,9 and 9

what is μ?

Here: 1+2+3+4+5+5+6+6+7+7+8+9+9 =72

13 ----> Total of Numbers

72/13=5.53=μ

Of course there are more complex methods, but this is the basis.

Hope it helped ;)
