Question

Quizplus · Accepted Answer

The chi-square test is used to determine if there is a significant association between two categorical variables. Choice B, which examines the relationship between satisfaction with K-12 schools (a categorical variable: satisfied or not) and political party affiliation (another categorical variable), is suitable for analysis with a chi-square test. Choices A, C, and D involve continuous data (height, weight, amount willing to spend, and income), which are not appropriate for chi-square tests.
