Title: Washington State Achievers Longitudinal Surveys, 2000-2007

Online Analysis Using SDA

The online analysis system allows you to run both simple and complex analyses, recode and compute new variables, and subset variables or cases for downloading. The software powering the system, named Survey Documentation and Analysis (SDA), was developed by the Computer-assisted Survey Methods Program (CSM) at the University of California, Berkeley.

Weight

Please note that weights may affect analysis results.

In this study, the entire population of Achievers and the entire population of non-recipients were asked to participate in the survey, so weights were only needed to compensate for sub-population differences in non-response to the survey. For the cross-sectional datasets (baseline, first follow-up, second follow-up), the weight variable is called "WEIGHT" and for the longitudinal datasets the weight variables are "R1TO3WGT" (Cohort 1) and "R1_2WGT" (Cohort 3), respectively. For more information on weighting procedure, please refer to the weighting section of the documentation.
