What is SDA and why should I use it?

The Survey Documentation and Analysis (SDA) system allows users to conduct statistical analysis quickly and efficiently on the Internet using their Web browser. It 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 crosstabulation to multiple regression and analysis of variance. The system allows users to design and implement custom recodes as well as generate subsets of data for download and analysis with traditional statistical applications.

For an overview on how to analyze data online, please consult our SDA Tutorial.

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