Quizplus · Accepted Answer

Random assignment helps reduce the effect of confounding variables by ensuring that participants are assigned to groups in a way that is not influenced by any other variables that may affect the dependent variable. Random sampling can also be helpful in reducing the effect of confounding variables, but it specifically addresses the issue of selecting a representative sample from a population, rather than assigning participants to groups in an experiment. Utilizing several dependent variables and conducting a quasi-experiment may help to control for confounding variables to some extent, but they are not as effective as random assignment.
