APFIVE Advantage of Experimental Over Correlational Design
Why would an experimental method involving random assignment be preferred over a correlational study when investigating the effect of group study sessions on test scores?
A
Experimental methods require fewer resources and are less time-consuming than correlational studies overall.
B
Correlational studies are less efficient at handling large groups required in studying group dynamics like study sessions.
C
Random assignment helps establish causality by controlling extraneous variables that could confound results.
D
Random assignment increases the external validity of findings from group studies beyond controlled environments.
