A researcher wants to create an intervention to improve the well-being of graduate students in a counseling program,so she gives one group of students specific doses of rocky road ice cream,the second group of students specific doses of licorice,and the third group of students specific doses of chewy fruit-flavored candies for their treatments.As a second factor,she includes students in their first semester of their first year of graduate school as one cohort and students in the first semester of their second year of graduate school as the other cohort.To analyze the differences in well-being between the students in the three different "treatments" and two cohorts,she would use a(n) ______.

A) analysis of covariance
B) analysis of variance
C) factorial analysis of variance
D) repeated-measures analysis of variance

Factorial Analysis

A statistical approach that explains the variance among observed, correlated variables by a smaller set of unobservable variables known as factors.

Well-Being

A comprehensive term for the condition of an individual or group, encompassing physical, psychological, and social aspects.

Cohorts

Groups of individuals sharing a common characteristic or experience within a defined period, often used in studies to examine the effects over time.

Final Answer :
C
Explanation :
The researcher is manipulating two independent variables (the type of "treatment" and the cohort). Therefore, a factorial analysis of variance is the most appropriate statistical analysis to use. This will allow the researcher to examine the main effects of each independent variable as well as any potential interaction effects between the two.
