I am unsure about how to interpret the output box I get doing an ANOVA in SPSS. That's the "Tests of between-subject effects" box. I had 2 groups (A and B), and 2 results (EnergykJT0 and EnergykJT1). I used EnergykJT1 as my dependent variable, groups as fixed variable and EnergykJT0 as covariate. In the output box I get a list of sources: corrected model, intercept, group, and EnergykJT0 with their sig. value. I am trying to identify which correspond to time, interaction, and treatment. My best guess is group=treatment, and the covariate=interaction? Don't know about time. I haven't worked with ANCOVA before, as it probably shows. Any ideas?
