If you
decide to answer all or part of this problem set, you can obtain up to three
(3) percentage points of extra credit toward your final grade. That is, whatever you obtain on these
problems (out of 3) will be added to the grade you would otherwise
receive. Answering some or all of these
problems cannot lower your grade, but could raise it.

The
following problems ask you to analyze the connection between the variable *Future
– Economic Future* and some attitude/opinion variables in the *ssae98.sav*
file located in folder *t:\students\public\201*. The *Future* variable asked respondents to assess whether,
in twenty years, they believed they would be better off, worse off, or at the
same economic level as their parents are now (question 18). The following problems ask you to examine
the relationship between students’ assessment of their future and opinion
variables *V1*, views on free trade; *V6*, government helps business;
and *V8*, user fees for health care (from question 15).

- Obtain
frequency distributions for the four variables
*Future, V1, V6,*and*V8*, along with means and standard deviations for the latter three. Briefly describe.

- Use
*Analyze—Compare Means—Means*to obtain the means of each of*V1, V6,*and*V8*by*Future*. Again, briefly describe the patterns of the means, that is, comment on how those with different evaluations of the future respond to the three opinion variables.

- Obtain
a cross-classification of each of the opinion variables
*V1, V6,*and*V8*by*Future*. Request the chi-square statistic, along with the expected count. Describe your findings about the relationships between evaluations of the future and each of the three opinion variables. (To obtain the cross-classification table and chi-square statistic, request*Analyze—Descriptive Statistics—Crosstabs*and, using*Statistics,*check the*Chi-square box,*and using*Cells,*click on*Observed*and*Expected*).

- Use
*Analyze—Compare Means—One-Sample T Test*to obtain two tests of a mean. Test whether (a) the mean response of undergraduates to statement*V6*exceeds 3.5, and (b) the mean response of undergraduates to statement*V8*differs from 2. Describe the results.

- Write
a short summary report on what you found about the relationship between
*Future*and the three opinion variables. Comment on any similarities or differences among the results of questions 1-4.
