The 1992-93 National Study of Postsecondary Faculty (NSOPF-93), the second cycle of this study, surveyed institutions and faculty, with a sample of 974 public and private nonproprietary higher education institutions and 31,354 faculty members. The study was designed to provide a national profile of faculty, including their professional backgrounds, responsibilities, workloads, salaries, benefits, and attitudes. This manual was developed with the goal of providing analysts with the information necessary to use and interpret the NSOPF-93 public use files. Chapter 1 provides background information on questionnaire development, sampling, and data collection procedures. Chapter 2, the "Guide to the Data Files and Codebooks," contains information on: (1) content and organization of NSOPF-93 files; (2) identification codes; (3) variable names; (4) derived variables; (5) use of flags and weights; (6) notes on variance estimation; (7) using the Statistical Analysis System (SAS) and the Statistical Package for the Social Sciences (SPSS) to analyze the datasets; (8) a guide to hardcopy codebooks; and (9) a description of the NSOPF:93 electronic codebook for institution files. Eight appendixes provide information on data collection instruments, file record layouts, and codebooks. (Contains three exhibits.) (SLD)
