To learn more about the relationships among and between questions or variables, researchers require access to digital data files or datasets. A dataset contains every respondent’s answers to each question and variable on the survey in a format that permits statistical testing of causal relationships, and bivariate and mutlivariate crosstabulations.  Roper Center dataset files are available in ASCII and SPSS. RoperExpress service provides access to the Center’s digital data files on demand, including complete documentation with questionnaires, codes, methodological reports, and more.
