Salvucci, Sameena; And Others
This user's manual summarizes the results and use of design effects and generalized variance functions (GVF) to approximate standard errors for the 1990-91 Schools and Staffing Survey (SASS). It is Volume I of a two-volume publication that is part of the Technical Report series of the National Center for Education Statistics (NCES). The SASS is a periodic integrated system of sample surveys conducted by the NCES that provides information on public and private schools, public school districts, teachers, and administrators. The survey includes several types of teacher and administrator respondents. The 1991 SASS is a set of four related surveys dealing with teacher supply and demand, school administrator characteristics, information about schools and students, and teacher characteristics. This manual introduces the design effect and the GVF for estimating sampling variances for complex surveys such as the SASS. Appendixes contain: (1) variables selected for average design effects and GVF fitting; (2) average design effects tables; (3) GVF tables; and (4) a sum of weights table. (Contains 8 tables, 9 tables in the appendixes, and 33 references.) (SLD)
