    when a question ask you to work out b, where in the formula book let
    b=Sxy/Sxx

    some time the question can have any variable like p t h q etc...
    let say a question has Spp, Spt and Stt

    we would obviously do b= Spt/S...

    how doe we know what goes in the numerator which one goes in there???

    i now it a funny question
