Mean absolute deviation #=1.04#

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 :)
