Answer: 14.25
First we will find the mean,
(2+4+5+5+3)/2
=19/2=9.5
Now we will subtract all 5 numbers from the mean we found.
9.5-2=7.5
9.5-4=5.5
9.5-5=4.5
9.5-5=4.5
9.5-3=6.5
We will now find the mean for these new numbers, that is,
(7.5+5.5+4.5+4.5+6.5)/2
=28.5/2=14.25
THERE YOU HAVE IT, MEAN ABSOLUTE DEVIATION OR MAD. GOOD LUCK!
