All those white spaces are for last minute panic formula's that I've forgotten. Trust me, it will be full by the exam.

Shit, like sp!... Or have I done it? I cant think, its too early :p

Oh, and how to work out the SS of Interaction. DF is easy, but have we even learnt how to calculate SSI?

it is the same as before, (n-1).sd^2. thats the standard deviation of all observations. "total" sums of square is referring to the residuals squared....you'll find both n and sd in the bottom right corner of the tabulated statistics.

I saw your name on the list in the room (I had to check my seat because someone else decided to sit in it and I had to get them to move), but didn't have the time to stalk you! :p

Yeah, the exam was pretty good. Totally fine up until the last question when I couldnt for the life of me work out the df from A, B, I and E. Sat there for a good 10 minutes trying to work it out, but couldn't. With 20 mins to go, I did what I could of the calculations, and worked out which one needed to be done for the multi comparison. And then 5 minutes before the end, it all clicked. Luckily the calculations I did before (bar obviously the DF and therefore p-value) were right, so I was pretty relived. Stopped dead on "pens down".

It was my last exam too, still waiting for it to sink in though. Still feel like I have study hanging over my head.

Ta for all your help this semester, it was greatly appreciated! :D
