find the mean
by adding them all up and dividing by the amount of numbers that are there
so if I have
5,6,7,8
I would add them up and divide by 4
now we subtract the mean from each of the numbers and take the absolute value
add them together
then divide by how many there are
so
5,6,7,8
5+6+7+8=26
26/4=6.5
now I do
5-6.5
6-6.5
7-6.5
8-6.5
taking the absolute value of each one means you will take the positive version of that answer
so -1 becomes 1
|-1|=1
then you add them all up so we get
1.5+0.5+0.5+1.5=4
then we divide by how many there are which is 4
4/4=1
the equation I have explained it
\[\frac{ \sum_{}^{}|x=\mu | }{ N }\]
where
µ is the mean of the given numbers
and N is the amount there are

so it's 14.4
