Question

Quizplus · Accepted Answer

Control groups ensure that the observed effect is not due to alternative explanations, and random assignment ensures that any differences between groups are due to chance rather than pre-existing differences in the participants. This allows for the identification of causal relationships between variables. Self-selection and informed consent are important ethical considerations but do not necessarily improve the validity of the research design. External validity and dependent variables are important concepts in research, but they do not directly relate to the benefits of experiments for establishing causal relationships.
