An independent-samples t-test was run to determine if the Mind Over Matter coping strategy was more effective at reducing anxiety than deep breathing exercises. The results showed that the participants using the Mind Over Matter strategy (M = 21, SD = 2.2) reported lower levels of anxiety than participants using deep breathing exercises (M = 28, SD = 2.7). This difference was significant (t(19) = 4.37, p < .01).
