What is SDA and why should I use it?

The Survey Documentation and Analysis (SDA) system allows users to conduct statistical analysis online. SDA was developed by the Computer-assisted Survey Methods Program (CSM) at the University of California at Berkeley. The SDA system is capable of performing a wide range of statistical analyses from bivariate cross-tabulation to multiple regression and analysis of variance. The system allows users to design and implement custom recodes, and generate subsets of data that can be extracted from SDA and imported into other statistical software for further analysis.

For more information on SDA, please consult the Online Analysis Using SDA page.

Additional information about SDA and its capabilities can be found in the SDA online documentation from the University of California at Berkeley.
