Question

I need help help pls

Answer 1

MAD = 2

Explanation:

First We'll find the mean of data

Mean =
`(20)/(5)`

Mean = 4

Then, we'll find absolute deviation

=> |4-3| = 1

=> |4-2| = 2

=> |4-1| = 3

=> |4-1| = 3

=> |4-3| = 1

Now, taking the mean of these absolute deviations:

MAD =
`(1+3+3+2+1)/(5)`

MAD =
`(10)/(5)`

MAD = 2
