Experimental Research Questions
The role of random assignment in controlling for confounding variables in experimental research is to ensure that participants are assigned to different groups or conditions in a completely random manner. This helps to minimize the influence of any potential confounding variables that may affect the outcome of the study. By randomly assigning participants, researchers can assume that any differences observed between groups are due to the manipulation of the independent variable, rather than any pre-existing differences among participants. Random assignment helps to create comparable groups, reducing the likelihood of confounding variables impacting the results and increasing the internal validity of the study.
