Online Analysis

Users can perform online data exploration and analysis on the CPES data without downloading files by using the Survey Documentation and Analysis (SDA) system developed and maintained by the Computer-Assisted Survey Methods Program at the University of California, Berkeley.

SDA allows users to:

  • Review frequencies or summary statistics of key variables to determine what further analyses are appropriate
  • Review frequencies or summary statistics for missing data
  • Produce simple summary statistics for reports
  • Create statistical tables from raw data
  • Create a subset of cases or variables
  • Browse an electronic codebook
