To find this take the average of the absolute values of the differences between each member of a data set in the mean of the data set

See Explanation

Step-by-step explanation:

The question is incomplete, as the dataset is missing; However, one can deduce that the question implies that you calculate the mean absolute deviation of the missing dataset.

Take for instance, the dataset is: 1, 2, 2, 3, 3, 5, 8

Calculate the mean:

Next, proceed to the instruction in the question;

Which is:

So, we have:

Remove absolute brackets

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
