Describe and compare correlational research and experimental research. What key advantage does experimental research have over correlational research?
What will be an ideal response?
Answer: A good answer will include the following key points.
? Correlational research involves measuring the degree of association between two or more variables.
? It involves calculating correlation coefficients, which indicate the strength and direction of an association.
? Correlational research cannot be used to determine causation. The experimental method is the only technique that can provide strong evidence for cause-and-effect relationships.
? In an experiment, subjects are randomly assigned to two or more groups, which differ only by an independent variable which the experimenters manipulate.
? Experimenters then measure one or more dependent variables and compare them across the groups.
? This allows researchers to determine if manipulating the independent variable has an effect on the dependent variable.
