Experimental design provides the strongest cause-and-effect argument because it involves manipulation of an independent variable and random assignment of participants to groups. This enables researchers to establish a cause-and-effect relationship between the independent variable and the dependent variable. In contrast, quasi-experimental design lacks random assignment and pre-experimental design lacks both manipulation and randomization, while correlational design only allows for the analysis of the relationship between variables without being able to establish causation.
