Percentage of People Wearing Masks Correctly On Campus at CU. Figure shows the observed differences between masking indoors (left) and outdoors (right) on campus at CU (p < .001). A Bonferroni correction was used to compare masking behaviors indoors vs. outdoors on campus. The frequency of correct masking was higher indoors compared to outdoors (p < .001). Conversely, the frequency of incorrect and no mask usage was higher outdoors compared to indoors (p = .006 and p < .001, respectively).
