Appendices for “Academic Peer Effects with Different Group Assignment Policies: Residential Tracking versus Random Assignment”

In table 1 I report mean values of selected student characteristics that are determined prior to university attendance, separately by tracking/random assignment period and by dormitory/non-dormitory status. I report p-values from testing if these means are equal across dormitory students in the tracking and random assignment periods (column 4) and across non-dormitory students in the tracking and random assignment periods (column 7). I also report pvalues in column 8 from testing if the changes in means between the tracking and random assignment periods are equal for dormitory and non-dormitory students, i.e. testing if the parallel trends assumption holds. There are differences in three of thirteen characteristics that are significant at the 10% level. However, two of these differences are due to omitting one non-randomly assigned dormitory in the random assignment period, as I discuss in section I.
