A researcher wants to create an intervention to improve the well-being of first-semester graduate students,so she gives the professional school counseling students specific doses of rocky road ice cream and the mental health counseling students specific doses of licorice.To analyze the differences in well-being,she would use a(n) ______.

A) dependent-samples t test
B) analysis of variance
C) independent-samples t test
D) repeated-measures analysis of variance

Since the researcher is comparing two different groups (professional school counseling students and mental health counseling students) who are receiving different interventions (rocky road ice cream vs. licorice), the appropriate statistical analysis would be an independent-samples t test. The dependent-samples t test would be used if the same group of participants were being compared before and after an intervention, while the repeated-measures ANOVA would be used if multiple groups were tested over time. The ANOVA would not be appropriate for this scenario as there are only two groups being compared.
