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.

Please note that weights may affect analysis results.
When analyzing the pooled sample, the research team used weights to correct for the fact that the proportion of program and control group members varied by income tier. Without weights, the control group in the pooled sample would contain a high percentage of sample members from Tier 1, the lowest income tier, while the program group would contain a high percentage of sample members from Tiers 2 and 3, the higher income tiers. Weights were not used when analyzing the income tiers separately.
The variable WAWGT is the weight used for such pooled analyses for the full sample, the variable WAWGT_NUMCH is the weight used for the pooled sample in the "number of children" subgroup runs, and the variable WAWGT_EMPPY is the weight used for the pooled sample in the "employment in prior year" subgroup runs. For more information about weighting, please refer to the User Guide.
