Use the General Social Survey data to find the valid percentage of Americans who said that they were very satisfied with their job or housework (SATJOB). Next, find the cumulative percentage of people who say that their family income in 2010 was below $50,000 (INCOME06). Why do you think that family income for a survey in 2010 was reported in 2006 dollars? Choose another variable and comment on some aspect of it. Hint: To obtain nationally representative estimates, the data set must be analyzed with the weight “on.” Weight cases by selecting DATA, then WEIGHT CASES, and finally WTSSALL. The frequencies procedure in SPSS can be located by clicking on ANALYZE, then DESCRIPTIVE STATISTICS, and finally FREQUENCIES.
