Question

Can someone please help me find the mean absolute deviation of these numbers: 15, 17, 15, 17, 21, 23

Answer 1

Explanation:

mean absolute deviation=(|x-mean|)/number of terms.

`mean=( 15+17+15+17+21+23)/(6)=(108)/(6) =18\\x ~ |x-mean|\\15 ~3\\17 ~ 1\\\\15 ~3\\17 ~1\\21 ~3\\23 ~5\\\sum=16\\mean~absolute~deviation=(16)/(6) =(8)/(3) =2 (1)/(3)`
