Respuesta :

add all the numbers and then divide by how many there are in the set to find the mean so

-11+22+-2+-3=6

6÷4=1.5

so 1.5 would be the mean

Hope this helps!

In order to find the mean, add up all of the numbers and divide the sum by the amount of the numbers.  So, -11+22+(-2)+(-3)=11-2-3=6.  Now, divide 6 by 4, (the amount of #s).  6/4=3/2 or 1.5.  So 1.5 is the mean of the set of numbers.

Hope this helped!
