Final Answer :
D
Explanation :
Analysis of variance (ANOVA) is the appropriate procedure when examining the differences in group means among three or more groups. ANOVA allows for the comparison of variance within and between groups to determine if there are significant differences in means. Pearson correlation is used to analyze the relationship between two continuous variables, the dependent-sample t test is used to compare means between two related groups, and regression is used to examine the relationship between a dependent variable and one or more independent variables.
