Both causal-comparative and experimental research attempt to establish cause-effect relationships. In causal-comparative research, the researcher attempts to identify potential causes for observed differences between groups, while in experimental research, the researcher manipulates an independent variable to investigate its effect on a dependent variable. Random assignment is a feature of experimental research and not of causal-comparative research, and while both types of research examine relationships after events have occurred, this is not a defining characteristic of either.
