    NB: i have just found the deviation (or difference) this is not that same as the standard deviation

    I guess that I am confused. Do I need to find the deviatioin to the number 4 which is the hightest number in the data set?

    the Standard Deviation is the deviation of the squares

    I am still confused about that part, but atleast I understand how you arrived at the deviation (or the difference). Thank You very much!
