Dataset Files The most common method to obtain crosstabular results of surveys is to order a copy of the dataset from the Roper Center and run computer analysis on the study using a statistical program like SPSS , SAS, or STATA. These popular social science statistical software packages are relatively inexpensive and easy to use. They can also simplify what could be a very complicated process. Should you find you need assistance in bringing an ASCII data file into SPSS, however, directions are available.
Interactive Data Exploration and Analysis System-or IDEAS exist for a sampling of datasets. This technology permits crosstabular analyses using simple point-and-click techniques.
Often survey organizations have provided the Center with basic tables that indicate how key subgroups responded to the substantive questions. This option requires contacting a member of the Center's staff who can access the paper file archive to provide you with the relevant data for a nominal fee.
