I am analyzing questionnaire information from two individual data files for my dissertation. The first data file (N=944) contains school, school principal, and head school counselor information. The second data file (N=26,150) contains student, parent, and teacher information. Both data files have school id, stratum, and primary sampling unit (PSU) in common. Neither "match cases on key variables" nor "cases are sorted in order of key variables in both data sets" populated when the usual merging data techniques were applied.
