The Experiment vs. The Correlational Study

Correlational Study:
Look for systematic relationships among variables of interest. Researcher sees if changes in one variable are accompanied by systematic changes in another variable
ADV: Useful to examine variables that cannot be manipulated.
DISADV: Since variables are not manipulated in correlational studies, it is not possible to determine cause-and-effect relationships.

Experiment Study:
Researcher manipulates one or more independent variables to observe the effects on the dependent variable(s).
ADV: can isolate cause-and-effect relationships between variables.
DISADV: May not yield information about real-life behaviors
