Numeric, or non-bibliographic, data constitute a key component of research in the social sciences.
Research@TC has a list of publicly available datasets on the Resources page of their website. Login with your Teachers College credentials to gain access.
Columbia University Libraries supports research based on the analysis of numeric data through the Digital Social Science Center (DSSC) in the Lehman Social Sciences Library. You can consult their research guides as well as schedule a one-on-one consultation on your specific research.
The Digital Futures Institute at Teachers College also provides instructional sessions in using statistical analysis software for quantitative data. Check their calendar for upcoming workshops and tutorials.
