Question

Please help me find MAD for this

Answer 1

I know I'm 10 days late on this, but the answer is 1.5

Explanation:

1. Add 3+7+4+2:

`3+7+4+2=16`

2. Divide it by 4 because we have 4 numbers being added:

`(16)/(4) =4`

3. Subtract 4 from all numbers:

`4-3=1, 7-4=3, 4-4=0,4-2=2`

4. Add the differences:

`1+3+0+2=6`

5. Divide again by 4:

`(6)/(4) =1.5`
