Thank  you so much!

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

anonymous · Answer

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?

unklerhaukus · Answer

the highest score is 4
4 is a deviation of 1.7 from the mean (2.3)

anonymous · Answer

Okay that makes sense. how do the SD and the deviation differ?

unklerhaukus · Answer

the Standard Deviation is the deviation of the squares

anonymous · Answer

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