Notes: N= 7,010. For each covariate, the table displays the means prior to matching over means after matching.
N denotes the pre-matching sample size. A small number of observations were off the common support: Faculty social: 15 cases (10 control, 5 treatment), Faculty Academic: 3 (2 control, 1 treatment), Study Groups: 12 (8 control, 4 treatment), Clubs: 60 (59 control, 1 treatment).
