<Hi, I'm trying to enter values of n, Ex (sorry don't know where the sum notation symbol is on Ipad), Ex^2, Ey, Ey^2 and Exy into my calculator but unable to do this. I'm fine entering data both raw and frequency then finding the above results. However, what if I am only given summarised data, how do I find r, mean, sd etc?
Many thanks for any help offered.
