- Einspruch, E.L., 2005, pp. 61-90.
B)  working with SPSS, make exercise 8 (Einspruch 2005: pp. 87-88).

SPSS replication exercise week 9

Replication on basis of article on voter turnout (Blais and Carty 1990). Use your knowledge of Chapter 1-14. Use the Global Indicators Data. Save all your commands in the syntax.

Research questions:
a. Are there differences in voter turnout between three different historical periods in time? (see Blais and Carty, Table 1)

b. Are there differences in voter turnout between the different types of electoral systems? (see Blais and Carty, Table 3)

Question 1:  Formulate two null hypotheses and two alternative research hypotheses on the basis of the two research questions (see above)

Question 2:

Can you reject your null hypotheses? Are the differences significant? Use the appropriate techniques, the five-step model as a guide, and correctly interpret the results. Answer your research questions, and describe the results as you would in a formal research report.

Question 3:

Create a new variable of voter turnout that consists of three categories, namely ‘low voter turnout’, ‘moderate voter turnout’ and ‘high voter turnout’. Which countries are located in each category?

Question 4:

What is the bivariate association between voter turnout and the type of electoral system?
-       Describe the percentages. Use the Descriptive Statistics and Crosstabs and Cells command to create the correct Table

-       Does an association exist between voter turnout and the type of electoral system? Use the Chi-Square command to answer this question. See Chapter 11 in Healey for the calculation and interpretation of the Chi-Square

-       If an association does exist, how strong is it? Use the correct measures of association to answer this question. Use the Descriptive Statistics and Crosstabs and Statistics command.

-       What is the pattern and direction of the association?
