Hi there,
Perhaps a basic question about setting up contrasts, but I'm confused.
I have, for example, 3 conditions A, B, and C, one ev for each. B is a repeat presentation of A, but I
broke them appart to be able to probe differnces to repeats. I would like to perform the following
contrasts --
A + B
(A + B) - C
The first, I assume, is just 1 1 0. I also assume this would be the same as having had 2 evs, the
first ev = A+B with the contrast 1 0. Is this true?
As for the second contrast, is it 1 1 -1 or 1 1 -2?
thanks!
R
