Question #93371

Answer 1

Mean absolute deviation `=1.04`

Explanation:

1) Find the average of you data:

`(8+7+4+6+6)/5=31/5=6.2`

2) Find the distances between each of the numbers in your data set and the mean (ignore negative signs).

`8-6.2=1.8`
`7-6.2=0.8`
`4-6.2=-2.2=2.2`
`6-6.2=-0.2=0.2`
`6-6.2=-0.2=0.2`

3) Find the average of all of these distances:
`(1.8+0.8+2.2+0.2+0.2)/5=5.2/5=1.04`

`therefore` Mean absolute deviation `=1.04`

Hope it helps :)
