-Experimental Research: Explores cause and effect relationships
-Experimental Group: Exposes participants to the treatment
Control Group:Comparison for evaluating the effect. Experimenters compare the experimental group to the control group to determine if the treatment had an effect.
-The Bad: Low response rate, people lie, misinterpret themselves
Hawthorne Effect: The fact that you know you are in an experiment can cause change. (but the control group may even cause changes)
Correlation Method: Correlation expresses a relationship between two variables, it doesn't show causation.
