If you are interested in examining the relationship between the number of class days missed and one's subsequent semester grade point average, you would be best served to use a(n) ________ to study this relationship
A) case study design
B) correlational design
C) experimental design
D) naturalistic observation design
Answer: B
Rationale: Correlational research involves measuring the degree of association between two or more variables. In this example, the goal is to find the correlation between days missed and grade point average. Experimental designs can also be used to find relationships between variables, but are more complicated and they are generally only used when the goal of the research is to find cause-and-effect relationships.
