SPSS® Base 16.x Essentials for Social Statistics
The National Opinion Research Center (NORC) conducts a biennial national survey of American public opinion known as the General Social Survey (GSS). The data examples used in these tutorials employ either the GSS 2006 (23.4 MB) or the cumulative GSSs 1972-2006 (259 MB) data sets. Note that current University of Hawai'i students may download these data files, along with the GSS 1972-2006 Codebook (14.1 MB), directly from Laulima.
You can learn more about the General Social Survey at the official website maintained by the University of Chicago: http://www3.norc.org/GSS+Website/.
