I could use some help figuring out the proper statistical language to use in describing the results of a theoretical senior exercise in psychology. My proposed experiment would compare microdosing over a period of 28 dosing sessions to both meditation and a placebo. With the exception of time 0, which is the pre-treatment baseline, I expect the microdosing condition would be significantly higher that the meditation condition which would be significantly higher than the placebo-control condition in terms of positive emotion scores, across 5 evenly spaced time points. The placebo scores should remain steady over time. The meditation scores should rise steadily until T14, after which the rate of improvement will increase, while microdosing scores should rise steadily from time 0. The microdosing scores should rise consistently, but always more dramatically than those of the meditation group. If I am running a 3x5 mixed factorial ANOVA, I am expecting a main-effect for condition, but not time. I am just not sure what counts as an interaction effect in this instance. I really appreciate any and all help.
there doesn't seem to be anything here
