Three conditions are necessary for determining causality: empirical association, appropriate time order, and nonspuriousness. In an experiment, ten people who had frequent headaches participated in a study.  Five of the participants were given pain aides while the other five were given placebos.  Results were recorded. Discuss whether causality was established by meeting the three conditions.
