Analyze Data Online
Users can perform online data analysis on our Web site without downloading files. ICPSR currently offers online analysis components for selected data collections using Survey Documentation Analysis (SDA).
Please note that although most online analysis components are freely available to the general public, a few online analysis components are available only to ICPSR members.
Online data analysis allows users to:
- Search for variables of interest in a dataset
- 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 and charts from raw data
- Create a subset of cases or variables from a large collection to save time and storage space when downloading to a personal computer
- Browse the electronic codebook
