Chapter Ten Worksheet
Briefly describe the pattern in the results displayed in this table.
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Because both of these variables are ordinal, we need ordinal statistics. Write the significance level.
Is this relationship statistically significant? Yes or No. _____________
Do we reject the null hypothesis? Yes or No. _______________
Write the value of Kendall’s tau-b. Kendall’s tau-b = ___________________
Is there a pattern in those results? Do African Americans oppose capital punishment more than do white Americans? Yes or No. ___________________
Because race is a nominal variable, we need to use nominal statistics. Based on the chi-square test of statistical significance, what is the significance level here? Prob. = __________________
Is this relationship statistically significant? Yes or No. _________________
The null hypothesis is that there is no relationship between support for capital punishment and race? Do we reject the null hypothesis? Yes or No. _______________
Next, write in the value of lambda and the value of Cramer’s V for this relationship.
Lambda = _________________ Cramer’s V = _____________
Exercise 3:
Compare the column percentages horizontally. Is there a pattern? That is, do males and females differ substantially in their responses to this question about allowing an abortion? Yes or No. ____________
Because gender is a nominal variable, we need to use nominal statistics. Based on the chi-square test of statistical significance, what is the significance level here? Prob. = ____________________
The null hypothesis is: There is no relationship between support for allowing an abortion and gender. Do we reject the null hypothesis? Yes or No. _____________________
Is it more appropriate here to use nominal or ordinal statistics? Circle one.
Nominal Statistics Ordinal Statistics
Present the significance level for this relationship. Prob. = _________________
Is this relationship statistically significant? Yes or No. _______________
Do we reject the bull hypothesis? Yes or No. __________________
Which measure of association would be most appropriate here? Circle one.
a. Lambda
b. Cramer’s V
c. Kendall’s tau-b
d. Kendall’s tau-c
Present the value of the measure of association you selected above. ___________________
Is this relationship positive or negative? Circle one.
Positive Negative
Are the results in accord with the hypothesis? Yes or No. ___________________
Give a P-R-E interpretation of these results.
Exercise 5:
In this situation, is there a relationship between political distrust and the belief that elections cause government to pay attention to the people? Yes or No. _______________________
If you answered yes above, briefly describe the kind of relationship that exists between political distrust and the belief that elections cause government to pay attention to the people.
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Both variables are ordinal, so we will use ordinal statistics. The significance level for ordinal variables is presented on the last line of the statistics. Write in the significance level. Prob. = _______________
If we say that there is a statistically significant relationship between trust in government and the belief that elections cause government to pay attention to the people, what would that mean? That is, what decision are we making concerning these results based on a sample?
The null hypothesis in this situation is that there is no relationship between trust in government and the belief that elections cause government to pay attention to the people. Based on these, results, should we reject the null hypothesis? Yes or No. _____________________
Now let’s look at the strength and direction of the relationship. Because both variables are ordinal, we will use Kendall’s tau. Specifically, because both variables do not have the same number of categories, we will use Kendall’s tau-c. Write in the value of this measure of association.
Kendall’s tau-c = _________________
Is this relationship positive or negative?
Thus people who feel confident that elections make the government pay attention to them are more likely to have. Circle one.
Higher political distrust Lower political distrust
Give a P-R-E interpretation of Kendall’s tau in this situation.
Exercise 6:
Do the results mostly support the hypothesized pattern? Yes or No. ____________________
For which of the following groups are the results least in accord with the hypothesized pattern? Circle one.
Democrats Independents Republicans
Write in the significance level in the space provided. Prob. = ______________________
Is this relationship between part identification and 2008 presidential voting preference statistically significant? Yes or No. ______________________
The null hypothesis here is that there is no relationship between political identification and 2008 presidential voting preference. Do we reject the null hypothesis? Yes or No. ___________________
Write the value of lambda. Lambda = ____________________
According to lambda, by what percentage have we reduced the number of errors in predicting the dependent variable by knowing the independent variable? __________%
On the basis of those results, what would you conclude about the extent to which political party identification is related to voting preferences in the 2008 presidential election.
