Is there a relationship between age and support for traditional gender roles? Is the relationship between the variables different for different nations? The World Values Survey has been administered to random samples drawn from Canada, the United States, and Mexico. Respondents were asked if they agree or disagree that a university education is more important for boys than for girls. Compute column percentages and gamma for each table. Is there a relationship? Describe the strength and direction of the relationship. Which age group is most supportive of traditional gender roles (agrees with the statement). How does the relationship change from nation to nation?

Key Concepts

Cross-National Comparative Analysis

Cross-national analysis involves comparing data from different countries—in this case, Canada, the United States, and Mexico—to see if relationships between variables, such as age and support for traditional gender roles, change across different cultural or social contexts. This approach helps in identifying whether observed relationships are consistent or vary by nation, providing insight into broader socio-cultural patterns.

Nonparametric Statistical Methods

Nonparametric methods do not assume a specific probability distribution for the data and are especially useful when dealing with ordinal data. Techniques like computing column percentages and using the gamma statistic allow researchers to explore and validate relationships between variables without relying on the assumptions required by parametric tests.

Ordinal Association and Gamma Statistic

The gamma statistic is a nonparametric measure of association used with ordinal data, particularly useful when both variables have natural rankings. It quantifies both the strength and direction of the relationship between variables, such as age groups and levels of support for traditional gender roles. A positive gamma indicates that higher age groups are associated with greater support, whereas a negative gamma would indicate the reverse.

Contingency Tables and Column Percentages

A contingency table is a type of table in a matrix format that displays the frequency distribution of variables. Column percentages are computed within each column to provide the relative frequency of responses, facilitating comparisons across different age groups or other categories. This method helps in understanding how the distribution of support for traditional gender roles varies with age in each nation.
