correlation
Correlation does not indicate __________
causation
experimental studies involves both:
1.
2.
(1) the manipulation of one variable to determine its possible effect on another variable and
(2) control of additional variables that might potentially have an impact on the outcome; allows conclusions about cause-and-effect relationships
Correlational studies don’t enable?
conclusions about cause-and-effect relationships
In a good experiment a researcher separates and controls _________
variables

treatment groups
group of people in a research study who are given either no intervention or a placebo treatment that is unlikely to have an effect on the dependent variable
control group
research study that involves the manipulation of one variable to determine its possible effect on another variable, but without total control of additional variables that might have an impact on the outcome
quasi-experimental study
Experimental or Quasi-Experimental Study:
they don’t control for all potentially influential variables and can’t completely rule out alternative explanations for the results they obtain
Quasi-Experimental Study
