Solomon papers are completely different to the standard edexcel statistics papers, you guys shouldn't waste your time doing them now imo

You're right, my lady. No true knight fears imminent dishonour, humiliation and death.

I think so :P So, the regression line is effected by all types of coding? I always thought it was just multiplication + Div (but I realized that's SD).

It is affected unlike the PMCC ... so if it said the data was halved .. the regression line would be halved ... well i think so anyways ...
If I am wrong someone can correct me.
