Answer 2

I think that it is 10.

Answer 3

The mean is 10. But the mean absolute deviation is the mean of the distances of each number from that mean...confusing definition.

Answer 4

So 3, 5, and 8? @jwhite12

Answer 5

Where did 3, 5,and 8 come from?

Answer 6

Those are the distances between the numbers.

Answer 7

You need the distance between each number and the mean (10)

Answer 8

So the answer is 5?

Answer 9

I got a decimal. Did you find the 5 distances?

Answer 10

Oh so it would be 10.5?

Answer 11

What numbers are you using for the distances?

Answer 12

5

Answer 14

Ok your numbers are: 2, 5, 10, 15, 18.
We need to figure out how far each one of those numbers is from 10.

Answer 15

2 is 8 steps from 10
5 is 5 steps from 10...
