How do u find the mean absulute diviation?

Question

any number =n
sum=s

Answer 1

First you have to find the mean. After that, find out how far away each number is from the mean. If it is negative (for example, if you have six and your mean is four, it is the absolute value of negative four... which is four.). Then, you add all the differences up and divide it by the number of values.

Answer 2

i believe this is relative error your talking about?

take the accepted value - (the value you have)

either that or go to wikipedia
