Okay so the range is the largest number - the smallest number.
So 25 - 11 = 14
The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.
So we first calculate the mean.
119 ÷ 7 = 17
Now we calculate the distance each value is from 17. (SEE ATTACHMENT)
What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.
28 ÷ 7 = 4
The Absolute Mean Deviation is 4.
I'll figure out the bottom in a minute. But this is all I got for you so far.
