I've run a repeated measures ANOVA of some data, looking at the change in an outcome measure in 10 subjects outcome over time.
SPSS tells me that the within-subjects *effect* of time is statistically INsignificant (p=0.143). Yet it also tells me that the within-subject *contrast* (for quadratic trend) is significant (p=0.001).
What does this mean? How are the two conceptually reconciled?
