Question

Quizplus · Accepted Answer

Experimental research involves both random assignment of participants to experimental conditions and manipulation of the independent variable. Random assignment helps to control for extraneous variables and increase the internal validity of the study, while manipulation of the independent variable allows for testing cause-and-effect relationships between variables. Demonstrating correlations between variables is a feature of correlational research, not experimental research.
