Analysis of variance (ANOVA) is used when comparing the means of more than two groups. In this case, the independent variable is ethnicity (which has more than two categories), and the dependent variable is the frequency of going to the movies. Therefore, ANOVA is the most appropriate choice. T-tests and z-tests are used for comparing means between two groups, and chi-square tests are used for analyzing categorical data.
