This documentation has been prepared to guide the analyst who intends to analyze the data collected for the Safe School Study. Along with the Volume 2 Methodology report, its objective is to serve as a reference guide to the distributed data files. Together, these two volumes describe the data, the techniques utilized in their collection, and the procedures utilized in their analysis. Part I, Project-Level Documentation, is intended to focus attention on issues of general importance to all the files. It presents information pertaining to some or all the data files, provides an overall view of the data available from the study, and contains detailed sections on missing data treatment, weighting schemes, and data anomalies. Each section of Part II, File-Level Documentation, describes a specific data file. These sections consist of a brief description of the data, a codebook, and guidelines for using a specific file in analysis. Anomalies in the data collection process, ambiguities in the instruments, and special techniques required to process the data properly are also described. The final section of the documentation presents the programmer with a description of the software used in the study, as well as strategies useful for creating new analysis files with the Safe School data files. It also presents instructions for calculating a few unusual variables. (Author/MLF)
