If you decide to
answer all or part of this problem set, you can obtain up to four (4)
percentage points of extra credit toward your final grade. That is, whatever you obtain on these
problems (out of 4) 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 federal
political preference (variable *fv* – the last
variable in the data file) and some attitude/opinion variables in the *ssae98.sav*
file located in folder *t:\students\public\201*. Data on federal political preference come from
question 16 but have been re-classified into four categories: Liberal, NDP,
Conservative, and None. The following
problems ask you to examine the relationship between the federal political
preference of students and several opinion variables from question 15 of the questionnaire:
*V1* (views on free trade), *V2* (opinion about people helping
themselves), and *V8* (user fees for health care).

- First, obtain frequency
distributions and histograms for the four variables
*fv, V1, V2,*and*V8*. Also obtain the means and standard deviations for the latter three opinion variables. Briefly describe the distribution of responses. - Use
*Analyze—Compare Means—Means*to obtain the means of each of*V1, V2,*and*V8*, classified by*fv*. Briefly describe the patterns of the means, that is, comment on how those with different federal political preferences respond to the three opinion variables. For one of the opinion variables*(V1, V2,*or*V8*), obtain interval estimates of the mean for the four categories of*fv*. You could do this by hand or by using*Analyze—Descriptive Statistics—Explore*. (Under*Display*, clicking on*Statistics*eliminates the stem-and-leaf tables and, by clicking on the*Statistics*button in*Explore*, you can change the confidence level). Briefly comment on the results of these interval estimates. - Obtain a table for each of the
opinion variables
*V1, V2,*and*V8*, cross-classified*fv*. For each table, request the chi-square statistic, along with the expected count. Describe your findings about the relationships between federal political preference and each of the three opinion variables. (To obtain the cross-classification table and chi-square statistic, use*Analyze—Descriptive Statistics—Crosstabs*. 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*V2*exceeds 3, and (b) the mean response of undergraduates to statement*V8*differs from 2. Describe the tests and the findings from the tests. - Write a short summary report on
what you find concerning the relationship between
*fv*and the three opinion variables. Comment on any similarities or differences among the results of questions 1-4.
