A researcher is interested in knowing whether responses to lowering the legal age for drinking alcohol varies by gender. Which statistical test would be most appropriate for this type of data?

A) Chi-square test
B) Analysis of variance
C) t test
D) Pearson correlation

The most appropriate statistical test for this type of data would be a chi-square test, which is used to determine whether there is a significant association between two categorical variables. In this case, the two categorical variables are gender and response to lowering the legal age for drinking alcohol. The chi-square test will help determine whether there is a significant difference in the frequency of responses between males and females.
