Hi Sam, Good question. I originally guessed that the "simple effect" (I know some people on this list don't seem to care for that term, but it's always made sense to me) coefficients were in the same direction, such that the effect if Origin at Treat=hot was significantly different from zero, but n

Dear all, I was wondering if anyone could help solve a problem of a missing interaction effect!! I carried out a 2 x 2 factorial experiment to see if eggs from 2 different locations (Origin = 1 or 2) had different hatching success under 2 different incubation schedules (Treat = 1 or 2). Six e
