Ummm, unfortunately I don't understand this :o) I am by no means a mathematician. I am studying psychology and 1/4 of my course is statistics *for psychology*, ie it's pretty basic without any of the advanced stuff (I hope!). All I want to know, for interest's sake, is how one calculates the mean to z, larger proportion and smaller proportion of a standardised score, without having to read through a long list of numbers. Forgive me if that was covered in your FAQ, but I couldn't see it! Perhaps you could point me in the direction of the formulae?
