establish causality between variables by manipulating one variable and measuring its effect on another variable. Observational research can observe and describe associations between variables but cannot determine cause-and-effect relationships.
how to distinguish between quasi-experimental and nonexperimental research
Experimental research involves manipulating variables to determine cause-and-effect relationships, while correlational research examines the relationship between two or more variables without manipulation. Experimental research allows for greater control over variables and enables researchers to draw stronger causal inferences compared to correlational research.
