NAPP Online Data Analysis System

This is a preliminary version of our new online data analysis system. The system uses high-speed tabulation software developed at UC-Berkeley's Computer-assisted Survey Methods Program. We welcome feedback on any aspect of the system.

On the right frame of the following screen you will need to specify the following:

  • a row variable
  • a column variable
  • any "filters": filters can optionally be used to include only certain cases in your analysis
  • any "controls": controls can optionally be used to produce a separate table for each category of a variable
  • weights: the default is set to "person weight." Generally, this should not be changed.

Examples and screenshots are available in our short instructions page.
