Treatment combinations refer to the different ways in which multiple treatments or interventions can be applied simultaneously in an experimental design. In factorial designs, researchers systematically investigate the effects of varying levels of these treatments on an outcome, allowing for a more comprehensive understanding of how different factors interact with one another. This helps in identifying not only the main effects of each treatment but also the potential interaction effects that could influence the results.
congrats on reading the definition of treatment combinations. now let's actually learn it.
