I do have a rather simple question but could not find a direct answer on other forums.

I ran a repeated measures ancova with time (2) as within-subjects factor on accuracy rates (so that one was measurd twice) and entered age as the covariate.

in the between-subjects table the effect of age is singificant, how do I name this effect, is it the main effect of the covariate?

and further, does it mean that across levels, age has a different relationship to accuracy? (e.g. running a linear regression on mean accuracy with age as independent variable to interpret that relationship-this actually gives exactly the same p-value)?

I am highly desperate to receive an answer r at least half an answer and would be very grateful for any help, Thank you!
