mate - this has been asked countless times - I can't recollect there being an answer tho ahaha Have you checked the textbook?
sorry I just got back from chemistry and do S1 straight away so havent check, that case was like an extra number added, but what if we code like v=x/1000, would it matter ??

I'm so confused, because apparently they're all different for Sxx, Syy and Sxy
So, if you have a Coding where of say 2X+6, you ignore the +6. You multiply the Sxx by 4 (because that's 2^2), You multiply the Sxy by 2, and you don't multiply the Syy. That's what I saw from someone else. PMCC remains the same always.
Yes, that would be an example of when you would use that method.
So Sxx = multiply by n^2 Sxy = multiply by n Syy = no effect
Also are you 100% certain because I cant find much regarding this?

so like if you got x=2a+6, Sxx= 4 Saa, y=4b+1, Syy= 16 Sbb , and Sxy= (2x4=8) Sab ?? just checked it in one example and it didnt turn out right
I cannot claim I am 100% certain. But I have seen a couple of people say this. Is there an example Question anywhere?That's exactly right. An example of this being used in Question 2 of Jan 2008.
I think that is right. Could I have a look at the example?
